I think multiple papers could be written on the complicated behavior patterns and etiquette of urinal selection. Men are weird in the bathroom.
So if someone is already at a urinal, and you would have to take a urinal right next to them, then you should jump to a stall. But of course, only if there’s more than one stall open. You don’t want some poor bastard that has to poop to have wait on you just so the guy at urinal #1 doesn’t get freaked out.
Spacing rules do not apply to stalls, unless said stall has no door, and then you do everything possible to not walk past, exposing that poor, vulnerable, soul.
So no doors really breaks down the whole system. It just becomes like a disturbed ant pile, rapid, awkward, milling bodies everywhere. Each trying not to make eye contact or touch each other in any way.
I’m only mostly joking
