women's restroom. Can't remember the name of the place.
There was a picture of a naked guy with something over his 'twig and berries' that could be lifted up for a peek. And when the person lifted it, it rang a loud bell in the main dining area.
We were there for a company party and a very innocent, prudish lady we worked with went into the restroom. The bell rang three times.
We had a pretty good laugh at that. She wasn't amused.
