I was at a gig and had to empty my bladder. It can happen to anyone, so I'm not too upset. Thing is, after I'd washed my hands, I went to the door. A sign said Now wash your hands. I did and went back to the door. It still said Now wash your hands. I washed them and went back to the door. It still said Now wash your hands. I was in there for hours with others wanting to get in. They slid a sheet of paper under the door for me to put over the sign, but every time I looked at it to see where to put the paper, I had to wash my hands. I tried to do it by feel, but it was in Braille. In the end they had to take the door off its hinges and spray paint the whole door without looking at it.
