It's nice living in country where nobody takes those rules seriously..
Was standing in the men's, once. Door opens, woman trots in, looks around, sees me, and blushes. So I ask: "Woman's full?" She nods, then simply uses the lavvy.
The only problem in this situation was that she was hoping the men's was empty. I've used the woman's, too, often enough. Simply say that the other privvy is full up, you really need to go, and will burst if forced to wait in line, and all will be fine, around here.
I just wonder: how can anyone be charged with 'being a pedophile' for using the restroom meant for another gender?
