I often find bathrooms that were around before ADA [0], and have since been retrofitted, have the worst designs. That's why I try to use the handy-capable stalls, or "suites" as I call them, whenever I have a chance.
Most newer bathroom designs seem sane to me, since they were designed with ADA compliance in mind. Except for airport bathrooms for some reason, where you have to cram yourself and your luggage into a stall that's the same size as any other stall outside of the airport.
I agree that the older, retrofitted bathrooms are indeed horrible designs. However, I completely disagree that newer bathroom designs are "sane". I have seen very, very few "sane" public bathrooms; usually they're just in fancy restaurants where they don't use the standard metal partitions, and instead spend a lot of money on real walls and tile and wooden doors.
As far as I'm concerned, any public bathroom where the partitions between stalls have any gap at all (especially about 12 inches as they usually are) are not sane. There is no reason for that gap; it's just creepy.
