I HATE when ppl knock on a bathroom door/stall when KNOWING someones in there.

"Like yea ik the door is locked and all but is there REALLY someone in there?" Like genuinely whats the point? If the door is locked more or likely SOMEONES IN THERE its not just locked for no reason. Id understand if they went to the bathroom saw it was lock came back again 20-30 minutes later and see its still locked and got suspicious but NOPE. Most of the time people just come up rattle the doorhandle then knock obnoxiously...and to top it all off WHAT DO I SAY TO THAT?? Like uh YAH IM TAKIMG A SHIT?? Like what do you want from me!
