Altitude, weather, accumulated fatigue, too fast a pace, cold, equipment and mistakes in choosing a programme all reinforce one another. Some of these factors can be prepared for in advance; others stay outside anyone&#8217;s control.<\/p>\n<h2>The main reasons people turn back<\/h2>\n<h3>Insufficient acclimatisation<\/h3>\n<p>Being able to move fast at low altitude does not mean you are ready to sleep at 5000-6000 m. Cutting out nights, arriving late or trying to rely on old altitude experience all raise the risk. For a first mountain of nearly seven thousand metres the full schedule usually makes more sense, while the short formats demand recent acclimatisation beforehand.<\/p>\n<h3>Too fast a pace<\/h3>\n<p>An early surge burns energy and makes recovery harder. The right pace can feel unfamiliarly slow, especially to a strong athlete. The aim is to still be able to function the next day, not to be first into camp.<\/p>\n<h3>Weather and the state of the route<\/h3>\n<p>Strong wind, severe cold, snow and poor visibility can stop even a well-prepared team. Contingency days add flexibility, but they do not create a weather window. Turning back in unsafe conditions is the correct outcome of managing risk.<\/p>\n<h3>Cold and mistakes in clothing<\/h3>\n<p>Getting dangerously cold often starts not with the lack of an expensive down jacket but with overheating on the move, damp layers, adding insulation too late or unsuitable gloves. Test your clothing system in training and be able to adjust it with gloves on.<\/p>\n<h3>Unprepared equipment<\/h3>\n<ul>\n<li>Crampons do not fit the boots.<\/li>\n<li>Boots rub or pinch the foot.<\/li>\n<li>The sleeping bag and mat do not let you recover.<\/li>\n<li>The headlamp goes flat quickly in the cold.<\/li>\n<li>The rucksack hurts when you carry a load at altitude.<\/li>\n<li>The food is impossible to eat on the move.<\/li>\n<\/ul>\n<h3>Choosing the wrong programme<\/h3>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Situation<\/th>\n<th>The mistake<\/th>\n<th>A more realistic approach<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>First experience of around 7000 m<\/td>\n<td>Choosing the Blitz to fit your holiday<\/td>\n<td>Consider the full schedule<\/td>\n<\/tr>\n<tr>\n<td>You have altitude experience from the past<\/td>\n<td>Treating it as current acclimatisation<\/td>\n<td>Assess your recent nights at altitude<\/td>\n<\/tr>\n<tr>\n<td>You are in strong shape<\/td>\n<td>Ignoring altitude experience<\/td>\n<td>Separate fitness from adaptation<\/td>\n<\/tr>\n<tr>\n<td>You would rather not carry a load<\/td>\n<td>Assuming porters will be there<\/td>\n<td>Book the carries in advance<\/td>\n<\/tr>\n<tr>\n<td>An inflexible air ticket<\/td>\n<td>Cutting out the reserve<\/td>\n<td>Leave a margin for the expedition<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h3>Concealed symptoms and the pull of the summit<\/h3>\n<p>If you say nothing about a headache, loss of coordination or a sharp drop in strength, the guide gets the information too late.

Moving too fast worsens your sleep, poor sleep reduces your appetite, lack of energy slows you down, and a long day makes the cold bite harder. So a debrief should look for the chain rather than for a single culprit.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>The start of the chain<\/th>\n<th>Where it can lead<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Unsuitable boots<\/td>\n<td>Pain &#8211; an altered stride &#8211; a slow pace<\/td>\n<\/tr>\n<tr>\n<td>Overheating<\/td>\n<td>Damp clothing &#8211; cold at the next halt<\/td>\n<\/tr>\n<tr>\n<td>An early surge<\/td>\n<td>Exhaustion &#8211; poor recovery<\/td>\n<\/tr>\n<tr>\n<td>A concealed headache<\/td>\n<td>A late assessment &#8211; fewer options left<\/td>\n<\/tr>\n<tr>\n<td>Excess weight carried<\/td>\n<td>Fatigue &#8211; falling behind &#8211; getting chilled<\/td>\n<\/tr>\n<tr>\n<td>An inflexible air ticket<\/td>\n<td>Pressure &#8211; giving up a sensible reserve<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>Talking to the guide<\/h2>\n<p>It helps to agree in advance which symptoms and problems are reported immediately. Do not wait for the evening briefing if you are losing coordination, cannot warm your hands or have slowed down sharply. Reporting early does not mean you automatically go down; it gives the leader more information.<\/p>\n<h2>A successful expedition without the summit<\/h2>\n<p>If a team turned back safely, stayed healthy and understood why, the trip can have been run professionally even without 6962 m. Promising the summit at any cost is not an advantage; it is a sign that expectations are being managed badly.<\/p>\n<h2>A matrix of what you can control and what you cannot<\/h2>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Factor<\/th>\n<th>What you can prepare<\/th>\n<th>What cannot be guaranteed<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Fitness<\/td>\n<td>Regular training<\/td>\n<td>Feeling good every single day<\/td>\n<\/tr>\n<tr>\n<td>Acclimatisation<\/td>\n<td>A programme profile that suits you<\/td>\n<td>That everyone responds the same way<\/td>\n<\/tr>\n<tr>\n<td>Equipment<\/td>\n<td>A tested set<\/td>\n<td>That nothing breaks<\/td>\n<\/tr>\n<tr>\n<td>Weather<\/td>\n<td>Reserve days and clothing<\/td>\n<td>A windless window<\/td>\n<\/tr>\n<tr>\n<td>Logistics<\/td>\n<td>A plan and written confirmations<\/td>\n<td>That there will be no delays<\/td>\n<\/tr>\n<tr>\n<td>Decisions<\/td>\n<td>Criteria and discipline<\/td>\n<td>The summit as an outcome<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>Good preparation reduces the number of controllable mistakes and leaves the team more resource for the things that change around it. It does not turn a challenge set by nature into a guaranteed service.<\/p>\n<h2>Questions to ask yourself before you pay<\/h2>\n<ul>\n<li>Am I ready to turn back when the guide decides?<\/li>\n<li>Do I have time for a full profile and a reserve?<\/li>\n<li>Can I carry my own load at altitude?<\/li>\n<li>Have I tested my kit in real conditions?<\/li>\n<li>Does my insurance cover 6962 m?<\/li>\n<li>Have I described my recent altitude experience honestly?<\/li>\n<\/ul>\n<h2>How to run a debrief after turning back<\/h2>\n<p>A debrief reconstructs the sequence of events; it does not hunt for a culprit. Record the actual nights, sleep, appetite, symptoms, pace, food, water, weather, how the equipment worked and the moment the decision was made. \u00abI wasn&#8217;t fit enough\u00bb is a weaker conclusion than pointing to where the pace began to drop and what happened before that.<\/p>\n<ul>\n<li>get feedback from the leader<\/li>\n<li>separate external conditions from decisions you controlled<\/li>\n<li>find the first link in the chain of deterioration<\/li>\n<li>choose no more than three main things to fix<\/li>\n<li>do not set a new date until you have recovered<\/li>\n<\/ul>\n<h2>The group and the logistics also shape the result<\/h2>\n<p>Different levels within a group call for enough guides and a clear procedure for splitting it. Before you pay, establish the size of the team, the guide-to-climber ratio and what happens if one person turns back. Hiding symptoms for the sake of everyone else is not acceptable: it makes the decision worse for the whole group.<\/p>\n<p>Lost baggage, an unconfirmed porter, an error on a permit or a delayed transfer can eat into both your reserve and your energy. Keep critical items with you, and treat services as available only once they are confirmed in writing. A logistical problem must never be papered over by speeding up the altitude schedule.<\/p>\n<h2>What to pass on before a second attempt<\/h2>\n<p>Tell the new team the route of the previous expedition, the highest point reached, the sleeping altitudes, the day and the reason for turning back, the symptoms, any medication, your condition after the descent and the leader&#8217;s conclusion. If the problem was the equipment, give the models and the circumstances. If pace was the limiting factor, give the section and how long you were moving.<\/p>\n<p>This information helps in choosing 17, 12 or 7 days, whether high-altitude porters are needed and how much support the team requires. After turning back for medical reasons, discuss the plan with a doctor who knows both your condition and the nature of the effort. A medical assessment does not guarantee acclimatisation, but a sales manager or a coach must not stand in for a doctor.<\/p>\n<p>A second attempt is stronger when specific causes have been put right, a reserve has been kept and you are once again ready to accept turning back. Wanting revenge is not in itself preparation.<\/p>\n<p>You can compare durations in the <a href=\"https:\/\/mountainguides.pro\/2026\/07\/27\/aconcagua-in-7-12-or-17-days\/\">article on 7, 12 and 17 days<\/a>, and prepare for summit day with the <a href=\"https:\/\/mountainguides.pro\/2026\/07\/27\/summit-day-on-aconcagua\/\">separate guide<\/a>.<\/p>\n<h2>Five phases in which the reason for turning back changes<\/h2>\n<p>The same problem means different things on the approach and in the top camp. An early setback can sometimes be put right with rest, by redistributing loads or by adjusting the pace. Above base camp there are fewer options left, and the consequences of a mistake show themselves faster.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Phase<\/th>\n<th>What tends to show up<\/th>\n<th>The decision that keeps options open<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Mendoza and entering the park<\/td>\n<td>Documents, delayed baggage, untested kit<\/td>\n<td>Close any critical gap before starting the route<\/td>\n<\/tr>\n<tr>\n<td>The approach through Confluencia<\/td>\n<td>Too fast a pace, rubbing, poor eating<\/td>\n<td>Do not turn the approach into a race<\/td>\n<\/tr>\n<tr>\n<td>Plaza de Mulas<\/td>\n<td>Inadequate recovery, the wrong pack weight<\/td>\n<td>Assess your reserves before the first altitude cycle<\/td>\n<\/tr>\n<tr>\n<td>Carries to the high camps<\/td>\n<td>Poor sleep, falling appetite, accumulated fatigue<\/td>\n<td>Report how things are changing and adjust the plan before the next night<\/td>\n<\/tr>\n<tr>\n<td>The summit attempt<\/td>\n<td>Cold, pace, wind, time and coordination<\/td>\n<td>Treat the descent still to come as part of the decision<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>A phase-by-phase debrief does not look for someone to blame. It shows the first place where the team lost its margin. If a problem became obvious only near the summit, it is important to go back over the preceding days and find the early signs.<\/p>\n<h2>Early signals before the high camps<\/h2>\n<p>Not every bad night or slow day means the expedition is over. What matters is the trend: is the person getting worse, do they recover after a rest, can they eat and drink, do they keep their normal coordination and do they follow the plan without the group constantly speeding up.<\/p>\n<ul>\n<li>The pace drops noticeably two days running<\/li>\n<li>A normal pack weight becomes an impossible load<\/li>\n<li>Someone stops eating or cannot get their fluid intake back<\/li>\n<li>A problem with boots changes the way they walk<\/li>\n<li>Clothing is regularly still damp after a stage<\/li>\n<li>Symptoms are concealed until the evening briefing<\/li>\n<\/ul>\n<p>These observations are passed to the guide as facts. This article does not make a medical diagnosis and does not propose a drug regimen. The sooner the leader sees a change, the more route options are still available.<\/p>\n<h2>How a programme creates a margin or eats it up<\/h2>\n<p>The seventeen-day programme includes the full approach, two altitude cycles and two contingency days. It does not guarantee adaptation, but it creates a profile of its own. The twelve-day and seven-day options require confirmed prior acclimatisation and should not be chosen simply because they fit a holiday.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Decision<\/th>\n<th>The margin it creates<\/th>\n<th>How the margin is lost<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>A gradual approach<\/td>\n<td>Time to observe how you respond<\/td>\n<td>A fast pace and no recovery<\/td>\n<\/tr>\n<tr>\n<td>An altitude cycle<\/td>\n<td>A test of sleeping high and of the load<\/td>\n<td>Treating it as an athletic test<\/td>\n<\/tr>\n<tr>\n<td>A contingency day<\/td>\n<td>Flexibility for weather or condition<\/td>\n<td>An excursion booked in advance, or an inflexible ticket<\/td>\n<\/tr>\n<tr>\n<td>A porter<\/td>\n<td>Less weight over an agreed section<\/td>\n<td>Expecting help that was never booked<\/td>\n<\/tr>\n<tr>\n<td>An extra guide<\/td>\n<td>The ability to split the group more safely<\/td>\n<td>Assuming one guide can lead two sub-groups<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>A comfort service is useful only when it covers a specific function. Premium accommodation does not compensate for insufficient acclimatisation, and a porter does not put right a programme that is too short.<\/p>\n<h2>The checkpoints of summit day<\/h2>\n<p>The main attempt is not judged by a single turnaround time. The leader checks, in turn, the weather, readiness at the start, the pace of the first hours, condition on the key sections and the reserve left for the descent. Distance already covered is not an argument for continuing once the other conditions have stopped being met.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Checkpoint<\/th>\n<th>What is assessed<\/th>\n<th>The faulty logic<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Before setting out<\/td>\n<td>Weather, kit, condition and the group&#8217;s readiness<\/td>\n<td>\u00abWe&#8217;re awake now, so we may as well try\u00bb<\/td>\n<\/tr>\n<tr>\n<td>The start of movement<\/td>\n<td>Pace, cold and how the clothing works<\/td>\n<td>Making up lost time with a surge<\/td>\n<\/tr>\n<tr>\n<td>Mid-ascent<\/td>\n<td>The trend, food, water and coordination<\/td>\n<td>Judging only by the distance to the summit<\/td>\n<\/tr>\n<tr>\n<td>The upper section<\/td>\n<td>Weather, time and the reserve for the return<\/td>\n<td>Treating the descent as a formality<\/td>\n<\/tr>\n<tr>\n<td>After the summit or the turnaround<\/td>\n<td>The make-up of the group and a safe return<\/td>\n<td>Relaxing before you are back in camp<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>The exact turnaround time depends on the date, the conditions, the camp you start from and the team, and cannot be set by a general article. You have to accept in advance the guide&#8217;s right to stop the attempt before an accident becomes obvious.<\/p>\n<h2>How a group raises or lowers the risk<\/h2>\n<p>A difference in pace is normal in itself, provided the support available can manage it. Before you pay, check the size of the group, the number of guides and what happens if one person turns back. A private group without extra leadership does not automatically gain the ability to split.<\/p>\n<p>The dangerous dynamic arises when someone hides their condition so as not to hold the others up, or when the strong members push the group to go faster. The pace is the leader&#8217;s decision, and medical and personal information is reported without the team voting on it.<\/p>\n<p>Where the logistics are arranged B2B, the client must have a leader of their own with the authority to turn people around. A ground coordinator, the mules and base camp are no substitute for leadership above Plaza de Mulas.<\/p>\n<h2>An external cause and the quality of the organisation<\/h2>\n<p>Bad weather can make the summit impossible even with the right preparation. That is an external cause. But the quality of the organisation is still assessed: was there a reserve, did the group get information, were there criteria for the decision, and did the descent start in good time.<\/p>\n<p>Delayed baggage, an error in a document or a service that turns out to be unavailable are looked at the same way. The event itself may be external, but the absence of a fallback plan, of written confirmation and of an early response belongs to the controllable part.<\/p>\n<h2>A template for a debrief by time<\/h2>\n<p>After you get back, reconstruct the chronology from the last normal day to the decision. The notes have to be specific: the camp, the sleeping altitude, the start time, the pace, sleep, appetite, water, weather, load, equipment, symptoms and what was reported to the guide.<\/p>\n<ol>\n<li>Identify the first departure from your normal condition or from the plan<\/li>\n<li>Record how the climber and the team responded<\/li>\n<li>Check whether things improved after the decision that was taken<\/li>\n<li>Separate the external cause from the response you controlled<\/li>\n<li>Choose no more than three changes before the next attempt<\/li>\n<li>Confirm your recovery before buying a new date<\/li>\n<\/ol>\n<p>\u00abI wasn&#8217;t fit enough\u00bb is not a conclusion without saying where and on what evidence. \u00abToo slow\u00bb is equally inadequate without the actual pace, the load and the condition. The more precise the data, the more useful it is to your next leader.<\/p>\n<h2>When a second attempt really is stronger<\/h2>\n<p>A new trip differs by more than its date. If the kit was the cause, it has been replaced and tested. If carrying weight at a given pace was the limit, the training reproduces that task. If the programme turned out to be too short, a fuller profile has been chosen. If the decision was medical, the return is discussed with a doctor who knows the person&#8217;s condition.<\/p>\n<p>A cause of \u00abweather\u00bb does not call for blaming your preparation, but it is still worth keeping your fitness and rethinking the margin in your calendar. A cause of \u00abthe mountain was closed\u00bb does not justify an immediate rematch without recovery.<\/p>\n<p>Being ready to repeat Aconcagua also means being ready to turn back again in the same objective conditions. If the only goal of the new trip is to put the previous result right at any cost, the risk of deciding too late goes up.<\/p>\n<h2>Pack weight, mules and porters<\/h2>\n<p>Mules carry the agreed load as far as Plaza de Mulas and do not work above base camp. On the high section you carry your personal belongings and a share of the group kit, or book porters in advance. The mistake is finding out what things weigh for the first time on the day of the carry.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Stage<\/th>\n<th>What to weigh<\/th>\n<th>What to settle in advance<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>The approach<\/td>\n<td>Your day pack and what goes on the mules<\/td>\n<td>Labelling, limits and access to critical kit<\/td>\n<\/tr>\n<tr>\n<td>The first altitude cycle<\/td>\n<td>Personal and group loads<\/td>\n<td>How they are shared among the team<\/td>\n<\/tr>\n<tr>\n<td>Moving camp<\/td>\n<td>The real weight of the complete set<\/td>\n<td>Whether a porter is needed, and on which section<\/td>\n<\/tr>\n<tr>\n<td>The descent<\/td>\n<td>The load remaining and the climber&#8217;s condition<\/td>\n<td>Who helps in the event of an early return<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>A porter reduces one specific load, but does not make anyone acclimatised and does not guarantee a suitable pace. Availability, the section, the weight and the price are confirmed before the expedition.<\/p>\n<h2>The forecast and decisions on the route<\/h2>\n<p>A forecast is used for planning; it is not a promise of a window. The leader compares several sources against the actual wind, visibility, snow and the state of the team. A cheerful icon on a phone does not override the weather you can see.<\/p>\n<p>The mistake can go either way: carrying on despite a deterioration, or giving up too early on the strength of one long-range forecast. The decision is updated as data comes in. You are given a clear explanation, but you do not get a vote on the dangerous option.<\/p>\n<p>A contingency day helps you wait if the energy, the services and a realistic chance of another attempt are all still there. If someone is exhausted, or no window appears, having a date in the calendar does not oblige anyone to go out again.<\/p>\n<h2>Food and water as part of your pace<\/h2>\n<p>A shortage of energy rarely looks like a cause of its own in the first few hours. It shows up later as a falling pace, feeling cold and losing concentration. Work out in advance which foods you can eat on the move and at altitude, and keep them within reach.<\/p>\n<p>A drinking plan takes account of the cold and the risk of things freezing. This article does not set a universal volume: needs differ, and the specific guidance comes from the team. In a debrief, record what a person actually ate and drank, not what went into the rucksack.<\/p>\n<h2>Telling a correct turnaround from a systemic failure<\/h2>\n<p>A correct turnaround follows from a criterion understood in advance or from a real threat: the weather, someone&#8217;s condition, the time or the route. A systemic failure shows itself earlier &#8211; the data was missing, symptoms were concealed, a necessary service was never booked, or the decision was put off after several warnings.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Outcome<\/th>\n<th>What to examine<\/th>\n<th>The conclusion<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Turned back because of wind<\/td>\n<td>Forecast, actual conditions, timing and use of the reserve<\/td>\n<td>An external cause, with the decision correctly made<\/td>\n<\/tr>\n<tr>\n<td>Turned back because of pace<\/td>\n<td>Preparation, load, acclimatisation and the early data<\/td>\n<td>Find the first controllable link<\/td>\n<\/tr>\n<tr>\n<td>Turned back because of boots<\/td>\n<td>The fitting, the training and symptoms before the trip<\/td>\n<td>Put the kit and the testing right<\/td>\n<\/tr>\n<tr>\n<td>One climber turned back<\/td>\n<td>The number of guides and the plan for splitting the group<\/td>\n<td>Assess the quality of the group arrangement<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<h2>What counts as running an expedition well<\/h2>\n<p>The summit is a sporting objective, but the quality of the process is measured by other things too. The group was kept informed, symptoms were reported in time, the services matched the specification, decisions were taken before the margin ran out, and everyone got back safely.<\/p>\n<p>This approach does not devalue 6962 m. It lets you distinguish what nature and physiology produced from the work of the operator and the climber. That is exactly what makes a debrief useful for the next attempt.<\/p>\n<h2>A short record of the decision<\/h2>\n<p>The leader notes the time, the place, the factors and the action taken. Nobody needs a legal document at altitude, but after the expedition a record like that prevents arguments from memory. It also helps you see what actually changed between the first warning sign and the turnaround.<\/p>\n<p>If the decision concerns someone&#8217;s health, no unnecessary personal details are disclosed in a public account. For their own future preparation, the climber keeps the detailed medical and route information and passes on as much of it as the next leader needs.<\/p>\n<h2>What to put on record before you even book<\/h2>\n<p>Some of the future reasons for turning back are already visible in the booking form. Give the operator the dates of your most recent altitude trips, the highest places you have slept, symptoms, the reasons for previous turnarounds, your experience of tents and the pack weight you have carried. This information is needed to choose between 17, 12 or 7 days and to work out the support required.<\/p>\n<div class=\"table-scroll\">\n<table>\n<thead>\n<tr>\n<th>Question<\/th>\n<th>The risk it reveals<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>When were you last at 5000+?<\/td>\n<td>Substituting old experience for recent acclimatisation<\/td>\n<\/tr>\n<tr>\n<td>Where did you sleep high, and for how long?<\/td>\n<td>Relying on a brief visit to a summit alone<\/td>\n<\/tr>\n<tr>\n<td>How did you recover?<\/td>\n<td>Hidden exhaustion after a successful trip<\/td>\n<\/tr>\n<tr>\n<td>What loads did you carry?<\/td>\n<td>Past experience that does not compare with the high camps<\/td>\n<\/tr>\n<tr>\n<td>Why did you turn back before?<\/td>\n<td>A controllable cause that keeps recurring<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/div>\n<p>An honest answer does not reduce your chances of taking part.

If a preparatory trip changed, an injury occurred or you fell out of your training schedule, that has to be reviewed in writing and in good time, before non-refundable services are bought.
