Employees Only?

I was looking at one of those Employees Must Wash Hands signs in a restaurant bathroom the other day, where it lists all the state laws about cleanliness, or whatever, and it made me think: How about everyone must wash hands? Can we make that a law? The amount of degenerates I see exiting stalls and walking right out of the bathroom is unacceptable. These people should be removed from general population and injected with whatever disgusting diseases are contracted through fecal matter. This is still the number one argument for having a bathroom attendant...
