> No amount of explanation will change the bad mood, I'm not going to suddenly get bright eyed and cheery because it turned out to be a scheduling error.

It won't & can't change your past frustration - sure. But do you have to take it forward to the new few hours as you are judging another person trying to find his means of livelihood?
