Women, have you ever gone into the men’s restroom all because the line to the women’s restroom was long?

When my wife and I visited Paris years ago, we came to the conclusion that the French consider the words 'men" and "women" on the doors to be merely "initial suggestions." If there was something inconvenient about the facility designated for their gender (either too crowded, or out of service) people used the other one: men in the women's facility and women in the men's facility. Nobody, neither the "visitors" nor the "home team", made a big deal about it.
