Shut the Door Man

What is it with men and public restrooms?  They leave them a mess.  They are always locking the key inside and they have a bad habit of not washing their hands before they leave.  One gentleman didn't even bother shutting the door while he was relieving himself.  A group of blue-haired grannies who were in for their weekly bridge club meeting got a full monty view of this guy while he was weeing in the loo.  Was he an exhibitionist or simply too lazy to pull the door shut?
