When I was in Atlantic City a few weeks ago, I had to go bad, so I went to the rest room and literally stood there for a good minute or two trying, but I couldn't do it.
Also, like 3 years ago I was on a trip with two friends and the bathroom door was busted, so there was a huge hole in the door that anyone going to the sink could see through, and initially I couldn't pee or poo in there, but I think I was able to at one point or another. Luckily that was only for a day or so.
