Far more importantly, when you enter a toilet and there are only 3 urinals and no one else is in there, do you troll and stand at the middle one, thereby preventing anyone else from using the other two urinals without them breaking the code of conduct of urinals, or do you go to one of the ones at the end?
I use the middle one and feel smug about it

it's very annoying. Going to a toilet to see all cubicles closed is like hell!
That's quite a shock when in mid flow.
