was in a truck stop in MN one time, early morning, just going in the stall in the ladies room, I got a quick glimpse in the mirror of a guy in another stall, closing the door.
I said, I think you are in the wrong restroom, and he said, Oh, I didn't know or something like that.
But he didn't leave!! SO I did. About 5 minutes later he came out. Weird.
