I've found they never knock. I hope the push-button lock doesn't pop out without me knowing it some time. They just grab the handle and yank on the door.

I usually pound on the wall...then knock on their door (the other bathroom) on the way out. They still haven't taken a hint.

Seriously rude. I do not want to walk in on any of them and although I can understand the ladies not minding walking in on me, no one wants that awkwardness in the workplace.

I always knock...never want to see anything or anyone.
