that happened to me the other weekend in a bar. after seeing how much i did not appreciate that, he apologized about three times inside and outside the bar. he should have dropped it instead of dwelling on it
When using a urinal, always leave at least one between yours and the next guy down unless the restroom is very crowded and abiding by the rule would result in more time missed of the game/show/party/etc.
I'm surprised it took 25 posts for anybody to mention this one.
