The times I have visited the US I have always been disturbed by how little privacy I feel like I have in a stall. I am sure I have made eye contact with dozens of people in US airports at a time that is not appropriate for either of us.
Europeans just need to stop being so terrified of the human body and being such prudes. /s
It's funny how Americans get endlessly bashed for being prudes about the human body, and then somehow on this topic they get bashed for not being big enough prudes about the human body.
Here's why that is: Americans simply get bashed no matter what direction they go on any subject. It's done solely to make the person doing the bashing or mocking feel good.
If the stalls went all the way to the floor, it would be decided by elitist snobs in Europe that that is prudish behavior and ridiculous because there's nothing shameful about going to the bathroom and it's a natural function of the glorious human body. It would go like this: ah those stupid Americans with their fear of the human body, and their overly private bathroom stalls. Dumb Americans are afraid to even know that there's another human in the next stall, even a 12 inch floor gap is too much, because there might be a foot over there somewhere. It's silly how uncomfortable Americans are about normal functions of the human body, they can't even tolerate a small gap in the bottom of the stalls.
Chill out, I also hate the squat stalls in remote train stations in Italy that are three times the size they need to be leaving you feeling super exposed while trying to balance but that wasn’t the question the original commenter asked.
