"Can two (or maybe more?) men share a urinal"
Some 50 years ago at an Office Christmas party where the toilet facilities were somewhat limited (one urinal and one toilet), late in the evening after more than one ale and the queue was lengthy, I was one of FIVE using the toilet. One at the front and two each side. When your back teeth are floating you have to go.
In more recent times at a food and wine festival the female toilet queue was its usual long length. I was using the gents urinal when a young lady came straight past us and entered a cubicle. If you gotta go, you gotta go!
My Wife comments that no ladies must sit down on public toilets, as she usually finds them in a mess.
Signs -Gentlemen - Please stand close as it is not as long as you
-Ladies - Please be seated during the entire performance.
