Flip,
The term "restroom" can lead to embarrassing happenings. A few years ago a friend of mine who is a priest was traveling through Europe with another priest and he told me they were in some small country looking through the old cathedrals and in one of the bus stations he really had to go bad. He saw the Restroom Sign and said he made a run for it and was half way inside with his pants down when he realized there were women and children laying on mattresses in the floor. It was a Restroom for people waiting for the buses.
