Pee Where You Please

Our mens restroom is a pretty busy place so it's hard for us to keep track of the bathroom key sometimes when the Ref Desk is really busy.  We had one gentleman who got so angry that our bathroom was occupied (the key was actually locked in) that he failed to visit the other three mens rooms in the building and chose instead to go to the stacks in the far corner of the library behind the elevator shaft to relieve himself.  He left us a nice big 'water' stain on the wall and the floor. If you think inebriated people's breath is bad, it's nothing compared to the stench of their urine.
