Has this ever happened to you? You desperately need to answer natures call for #2 and you close the door to the only stall to find urine and skid marks all over the seat and/or crap all over the inside of the bowl.
Probably the most annoying part is you know the person who did it was well aware of the fact that they left it this way.
Here's a simple request... lets try to make the world a better place one public bathroom at a time.
Clean up after yourself.
My rule is simple: whenever you open the door of the stall, on your way out, always assume that someone is waiting to come in.
Do unto others...
