Double take

I grew up on a farm and we have an outhouse. We also have a normal bathroom, with a shower and functioning toilet. But we do have an outhouse, and use it. no big deal. but I know it's weird to some city-folk. (btw, it's not like the ones at Oktoberfest, used by hundreds and smelling of disinfectant) Anyway, I had to look twice when I walked into the womens' room at the bowling alley and the first thing I saw was this:I kind of looked around and then realized that there was another door behind me. phew, that could have been awkward.
