Public restrooms give me anxiety. I never know how many stalls it'll have, if the floor is going to be wet (gross!), the condition of the facilities.

...is someone didn't flush?

Well, some of these things can't be helped but I did notice something in an airport that I think every public restroom should utilize.

Along the walkways where they had the public restrooms they had giant signs out in front and told you how many stalls were available. If one was in use the number would go down. Not sure if it was connected to the doors locking or not, but so cool!

It also listed how close the nearest restroom was in case that one was in full use. Brilliant!

We need to get this going for all public restrooms everywhere.
