I've actually been in a restroom that was similar to this and it was incredibly awkward. Instead of the doors being high up, they were incredibly low so that you couldn't help but look inside while someone was using the restroom. At that point, the doors are useless. Sure, it's nice to have our faces covered, but that's only so you can't see the deep-red embarrassment all over our faces while you're obviously staring at our underparts.
There's nothing worse than a bad public restroom. When you can find a good one it can really change the game. I still think about the Hard Rock Cafe's bathroom in Hawaii. Completely private, sealed off restroom doors. It felt like heaven. If heaven was a restroom. If it were, Hawaii sounds like the right place to put it, to be quite honest.
