It’s almost comical how often the customer is, in fact, not right.

At their worst, they have sky-high expectations that are never going to be met, are not interested in being agreeable or pleasant in order to facilitate that, and then expect to be given some kind of compensation when things inevitably go wrong (or so they say). In any service job, this is the makings of a person who will turn a workday into a nightmare. 

Nonetheless, the whole point of these kinds of industries is that, up to a point, these individuals have to be accommodated and dealt with in order to keep the business going. It is one of the more annoying sides of any customer-facing role, but learning how to deal with it in a way that minimizes drama is a very valuable skill. De-escalation saves on the headaches.

Unfortunately, there are some scenarios where there really is no winning. A customer just wants to get something that they are not going to be able to obtain, and everybody else is going to suffer the consequences. Enraging as it is, that is just the way that things go sometimes. The only thing that can be done is to move on by the next shift.
