Unfortunately, I have to say a loud YES to that. Dissing the operators is just plain rude and inappropriate. Trying to overload the elevators is dangerous and slows things down. I feel like a large part of this problem is that a lot of people have a feeling/sense of false entitlement. Being anti-social. And yes, rude.
To be honest, and to counter this - 99% of the time, 99% of the people and interactions were completely wonderful, courteous and good. 1% of nasty can undo a large % of good.
