I travel around the US working from different states/cities. The difference in behavior is astounding between the big and small cities. I have the absolute best experiences in small to mid sized towns, and in big cities everyone on the road and in person behaves sociopathically.

It’s often beyond even simple competition / selfishness. You routinely see people going out of their way to be mean even when it doesn’t benefit them. But switch towns and the whole situation is flipped.
