I have frequently seen women enter the men's public restroom when there is a long line for the women's restroom. However, the other day a man (dressed as a man) came into the women's restroom, entered a stall, sat down (at least he was courteous enough to sit and not stand), used the toilet, exited the stall, washed his hands and left the restroom as though it was the normal thing to do.
Do any countries, states or cities have laws regarding the use of public restrooms? If so, what is the law and location. Also, what is the penalty for violating the law.
