My college library has a bathroom in which there’s one stall and two urinals, but it’s also a general bathroom for anyone, and a sign outside the door says “For added privacy, please lock the door.”

Obviously, I don’t think this will pose any problems, but a teacher raised a concern that an exhibitionist might keep the door unlocked on purpose so a female can walk in while he’s at the urinal, which has no privacy barriers.

I think that point is arbitrary, considering the fact that an exhibitionist can already do that in any public bathroom.

Your thoughts?
