Are we just supposed to GUESS where he is??
First of all, there were only TWO restrooms; well, two in the immediate vicinity of this sign. The other was one of those "family" restrooms that I noticed nearby, obscured by a poorly marked door, so if you weren't looking for a family restroom, which most people aren't, this is what you see; men to the left, women to the right and a very confusing sign in the middle.
As I stood outside of the restroom waiting for Ed to come out, I watched everyone who walked in. Men just walked right on by, happily oblivious of anything but their mission to pee. Women, on the other hand, would stop, look at the sign, sort of tilt their head as if they were also thinking one of three?? and then walk into their restroom.
I decided at that moment that it was must have been a man who wrote the sign. Since I didn't see him in my restroom, and I didn't see him in the family restroom, I guessed there was only one place he could be; the men's room, which Ed later confirmed.
For a minute there, I thought I was going to have to place a bet and watch someone shuffle shells until a maintenance man popped out.
