This isnt even a gay thing, this is a social and privacy/personal space issue. Don’t pick stalls that are far apart because “it’s gay,” do it because other people might feel uncomfortable being near other human beings period (might get stabbed or robbed, might get harassed, or might just have extreme social anxiety - the most likely) while their privates are exposed and they’re in the middle of something.
Unless there are huge dividers between each one. Then it doesnt matter as much.
Similarly, people who write “a 100%” to mean “a hundred percent.”
What they actually wrote winds up being “a one hundred percent.” The “one” doesn’t disappear by putting “a” in front of it. If you want to write a hundred, write “a hundred.” It’s what you’re supposed to do for smaller numbers in the English language anyway.
