If amazes me that people were able to get this photo.

That is what it would look like out of the water. Aside from being alive.

If they're zipping up while walking out, that's 100% confirms it

Are the sinks inside the cubicles in America then?

What if you hear the flush of another person?

Maybe not.

For example, there may not be paper towels, just toilet paper and no bin. You wash your hands, dry them with toilet paper and then flush that down together with the rest.

Of course, I know what you said is what people think so my route is: Do the business -> Wash hands -> Dry with TP -> Flush the TP together with the rest -> Wait hand-washing equivalent amount of time -> Exit.

If it's single stall, maybe. There's no lock on the door, so this is a multi-stall bathroom and it's most likely someone else's flush.

What is pictured is known to me mostly only theoretically. Someone female presenting zipping up their pants! Definitely did a double take on that.

In my experience, a particularly drunk man at a sports bar.

Oh yeah it is a bit like those scenes! As if you just reminded me of that anime lol.

Hideyoshi, and the way there were treated, was far from the most tasteful portrayal of a gender non conforming character but helped my egg to crack for sure!
