I have met people who have a pathological tendency to complain, in fact it is a problem that reaches almost the level of disease, such as with compulsive accumulators or compulsive buyers or pathological gifts. In all cases these people do not realize that they have a problem and when the people around them finally notice that there is something strange and they point it out to them, well, they simply deny it or even fight to defend that they are right and that it is the world the one that is wrong.

In these cases you have to choose whether you want to "win a sterile discussion" or have an "economic gain", for which you can move on to strategies of apologizing, giving part of the reason to the customer's complaint, trying to make him feel that I win the discussion and try not to cause further disturbances for other clients. After all, he is a customer, not a friend, of course, it would be great if all customers became friends, but there is an old phrase worth remembering: "I am not a gold coin to be liked by everyone" Always There will be people who complain, who do not like our service (even if they cannot rationally explain the cause of their displeasure) and who may sabotage or boycott the initiatives that are taken in the business.
