The most unhappy, mad customers I have ever seen in a place were the women in Dick's Last Resort in Dallas, TX. They have a unisex bathroom that does not have a working lock on any stall in there. So, every woman had to take a freind to hold the door since the stalls were deep and you could not hold it and sit on the pot. The walls were covered with Maxim syle 'girly' pics. And every woman in the bathroom was mad at every guy at a urinal, which they had to walk past to get to the stalls, even if they did nothing at all. I went once when some out-town-friends asked to - never again.
“But, but, but... The unisex bathroom worked so well on Alley McBeal, how could women be so upset in real life?!!”
