I took this photo outside a bathroom at a local facility around Washington, D.C.
This truly is one of the most troubling signs I think you can find, especially when you have to do your thing.
Why you can't use the bathroom, even if you say pretty please, I don't know.
But I would say, Mr. Toilet here should put his hands down and let people in--for use and not abuse. ;-)
