There is some guy who must need to go bad, because he's waiting for the bathroom, and has already three times grabbed at the door and jiggled, despite clearly being able to see if someone left. Here's an idea: use the also single-occupant ladies room.
Then remove gendered signs?
@Kye I mean, the real solution is fixing those men and setting up the next generation of everyone to not be so terrible, but I guess as an easier start?
