- Considering the majority of the paper towel in the can comes from those who wash their hands, I doubt that the door is covered in Poo. Unless, of course there could be people who waddle out of the stall to wipe w/paper towel & put it in the can...I guess I see your point. Anything is possible.
- People do this because it is NASTY to touch the filthy poop door-handle w/freshly washed hands (DUH!)...placing a trash can by the door is the appropriate thing to do! Poo hands spread disease!
- To whomever keeps throwing your papertowel on the floor after you use it, please place in trash as that is the appropriate thing to do.
