I just realized that you can unlock the shower area from the outside. Now, that begs the question...what's the point in locking it now? Someone can just open it from the outside. Thus making your endeavor pointless. Let's say, for example sack, I have a guest over and play a prank on them. Now, that prank would get them all dirty and most likely sticky, thus requiring a shower. While taking a shower, it's best to not be pranked, correct? Correct. So, they go into the shower with the expectation that that little piece of plastic that sticks up into the ceiling is going to protect them from further pranks and embarrassment. BUT, since I can unlock it from the outside, there is no protection. Now the person in the shower has no hope of surviving if a prank is deemed necessary...they have no where to hide. No where to go. It's a small plastic box. Trust me. There's nothing they could do. It'd all be over. Naked prank times. What is the world coming to?
