I was in a local restaurant recently and noticed that it had two restrooms. They weren't marked as gender specific. I had to decide: the one on the left? The one on the right? Would the one on the right historically have been the ladies' room? What if a man sees me when I come out? I looked around to see if any shady characters might be watching, waiting. A man did walk up, said Excuse me (could have been "scuse"me) and just went in to the closest one, like it was no big deal. Maybe he worked there. So then I had to wonder if he'd put the seat down... Of course his choice left me no choice. So I used the other one. The seat was down, so I felt a little better about the situation.
