From this day forth, I declare that all bathroom doors must be created with clear external indication of their (un)locked status. Gone is the day where you'll have to jiggle the handle to see if the door is locked, knowing full well that you hate it when people do that while you're trying to finish your business. Forgotten is the day that you stood outside a closed bathroom door for five minutes waiting for someone to emerge just to have someone else more assertive than you try the door and go right into the empty lavatory. You, Mr. Bathroom Door Maker, can make this dream of knowing the (un)locked status of every bathroom door the moment it's encountered come true.
Airplane manufacturers figured this out long ago. Why hasn't everyone else? If there's one reason that I enjoy going on airplanes, it's because I always know if a bathroom is in use or not. Some airplanes even have overhead indicators that inform the entire cabin if someone is using the facilities. It's a truly excellent system.
Please bathroom door manufacturers of the world, answer my cry and let me know if someone is using the loo!
