Yeah, not sure why you've been absolutely blasted by downvoters. How is someone silently waiting for another to vacate a spot they've indicated they will soon be leaving some harsh, aggressive gesture?
Somehow, the silent, vague "pressure" that someone is also interested in something they've temporarily occupied is distressing. Public bathrooms must be hell for them.
Honestly, your point is way better than mine, and even you've received downvotes for it. Like, bathroom lines exist. Sucks if you have shy bladder, but that doesn't make the person behind you need to pee any less either.
Yeah, except you're standing in the doorway, literally the frame of the door, waiting for one specific toilet to become available because it suits your needs, in spite of the one next to it being available as well, and now everyone's gotta brush up against you to get in and out of the goddamn bathroom.
It's more like there's another toilet available at the other end of the terminal, and everything in this bathroom is occupied. Again, lines for bathrooms exist.
