By waiting, for them to shake hands your giving the guy time to get up and get to the door. If the horn blew and your briskly walk off the court right then and there, chances are he's still clapping for his team and only notices you as he sees your backs clearing the doorway, and that point your not worth his trouble. BUT if sees you sittin out there on the court, he 's not got time to think about and then actually do what he's thinking about and give you a peice of his mind.

Sure some of the real nut jobs are still going to do what they want, but getting your butt of the floor quickly after the horn helps reduce the likely hood.
