Personally, I've always thought it was insane we design our public bathrooms to put our pooping and peeing on display to anyone who walks by. I guess the puritanical were worried about what sins we might get up to if we had some actual privacy. Take away the banks of urinals and stalls with half inch gaps between the panels, and wouldn't you know it, all the issues about who gets to use which bathroom disappear. And, as an added bonus, you don't have to be embarrassed by a loud fart, smelly shit, or shy bladder.
