About ten years ago I was in the bathroom at the computer company I worked at at the time. I saw the Training Manager make a beeline from the "#2" stall to the door.
I never shook hands with him again...
Nasty.
Elimination techniques vary widely between men and women, a guy can go without touching anything but his zipper. Theoretically.
The ladies require a bit more hands on to tidy up.
I think we have a guy here that can top that. This has been about ten years ago but I was in the restroom and the guy comes out of the #2 stall and heads straight for the door. He also had a half eaten Hostress cupcake in his hand.
