Cruel but good point from BAE guy.
Too many Wannabes seem to believe that because you are a customer (or a customer's cadet), the school is supposed to pander to your every whim, grovel to get you to work, or fly !, and tolerate your misbehaviour.
The wrong attitude is not unique to training and similar to that of scum who hire in the belief that this gives them the right to abuse the aircraft and anyone who points out the error of their ways.
