i used to work in a student union which had (i think) 9 bars in it - one thing i had to do at the end of the night was check the toilets before we closed up, in case someone decided to stay behind & help themselves to the nights takings (the bar i did most shifts in had the main safe in the back office where all the bars takings were kept until morning)
both the ladies and the gents were a bit of a mess tbh, but the ladies was by far the worst, almost always there would be a few lurid coloured piles of sick, due to one alcopop too many, and it wasn't uncommon to find sanitary towels stuck to the walls & back of the doors in the cubicles, which is a bit disgusting imo. that beats the wee-soaked floor of the gents any day!
as with many places, girls were frequently found in the gents when theirs got too busy, but any bloke in the ladies faced an instant ban & their union card being removed from them - this is a practice that winds me up a lot & i feel is totally unacceptable, and therefore banned a few of the more frequent female offenders who were always found in the gents since they obvioulsy had the attitute that normal rules didn't apply to them
