Can't say I make a habit of observing other people in public restrooms. I go in, do my business and leave. The most I do in observing is, I look for potential threats.
This thread does remind me of a joke though.
A Marine and a sailor both enter a public restroom and use the urinals. Upon finishing their tasks, the Sailor goes to the wash basin and starts to wash his hands.
The Marine zips up his fly and heads to the door. The sailor speaks out and attempting to embarrass the Marine says, The Navy taught us to wash our hands after peeing.
The Marine responds, The Marines teach us to not piss on ourselves and leaves.
I never said I was a successful comedian.
