14. Eager (too eager?) bathroom attendants
Men using the urinals at many bars and clubs might be startled when a strong pair of hands grabs theirs shoulders.
Don't whip around with your zipper down ready for a fight -- it's just the bathroom attendant, who will put a hot towel on your neck and give you a quick shoulder rub -- for a small tip.
If you find this creepy, like many do, just say "no thanks."
