When I was young I used to go to concerts at Nissan Pavilion (now Jiffy Lube Live). The bathroom sinks were gigantic steel tubs that topped out about six inches below waist level and there were wraparound foot pedals to activate a spray of water from a pipe in the middle. Huge signs above the sinks read “SINKS ARE FOR HAND WASHING ONLY!” Of course if you wanted to piss between sets there was a line a mile long for a urinal…and a very short line to be one of a dozen guys simultaneously pissing into one sink.
