The place where I work has a restroom on each floor with two urinals and two stalls. That's it. Sometimes one urinal or both have been out of order.

Then, in a stroke of pure evil, they renovated the restroom and put doors on the stalls that go all the way to the floor and swing shut by themselves. Universally the way we know if a stall is occupied is by whether the door is opened. It took days for people to even figure out that the stalls weren't really in use because no one would ever do something as stupid as making stall doors that swing shut.

So now you've got a few choices. You can knock on both doors. You can try to open them, which is risky because unless you jiggle the knobs a little bit the doors won't actually lock, so you could open the door and someone could be in there. Or you can go to another floor.

I didn't include looking under the door because the doors go almost to the floor.

What really ticks me off about this is that it's creating a problem that's already been solved since the beginning of time. The doors swing open. It's really simple. We figured this out a long time ago and moved on. Making the door swing shut is actually more work.

It's so obvious that someone who gets it wrong has to be either stupid or evil.
