back in my old office on 5th Ave, our floor was full of mid-30's to late-40's men. That poor bathroom was destroyed constantly. People took so many shits there that you sometimes had to wait for one of the 7 or 8 stalls to become available. And it was always so lound in there with toilets constantly flushing, sinks always on, and peopel always grunting. I swore it was louder than the nosebleed section at a Mets game.
Anyways, all that shit put so much stress on the plumbing system that the custodial staff made a routine of going into each stall and flushing the toilets multiple times just to keep things clear and moving.
