I've known for my entire adult life that urinals aren't in stalls, but I never realized how open they are until I saw this scene in Big Bang Theory:
That's no good at all for if you're a shy pee-er, or if the need is less urgent (but you want to go before leaving on a long commute, for example) so it takes some time to get started. Other people are right there and can see you and look you in the eye. But if you're in a stall, all other people can see is that there's someone in the stall. You have more privacy, and, if you're shy, you can just close your eyes and ears and shut out the world.
Given the number of men in fields like architecture and construction and plumbing, I'm surprised no one has put urinals in proper stalls yet. And it also surprises me that men continue to use open urinals when stalls (i.e. with toilets) are available.
Can anyone shed light onto why people still choose to use urinals?
