Where was that?  I'm curious! 

Somewhere in north Texas.  Can't be more specific.  I was only there once on a trip.

If you google with     pointer setter restroom door*     , you will find lots of references to places that have these distinctive doors.

Transgenders go to whichever bathroom they have the equipment for, is my understanding. There are some special bathrooms for transgenders, but probably in Europe or New York or somewhere like that.

Have you ever had that moment when you really have to pee but you don't know which bathroom to go into and you're not sure you can wait for someone else to go in or come out?

My favorite coffee shop used to have single-serving bathrooms labeled "lattes" and "mochas". 

In Belgium, the public restrooms have an attendant you have to pay before you go in, she's known as "Madame Pee Pee"  My sister made sure to warn me - and equipped me w/the proper amount of Euro change to give her!  (and you CANNOT decline to pay her... you gotta Pay to Pee!)

miranda! i went to belgium with my ex (not ex at the time) and he forgot to tell me. cause i didnt understand what she said i just went in. she was so pissed and i didnt get why. he had to go and apologize and tip her extra that time! HAHAHA
