Do you know why public toilet doors don't touch the ground?

Someone can lend you a helping hand. 

No, I do not mean it that way. At all. I'm talking about another need in a public restroom - toilet paper! If you haven't run out of toilet paper in such scenarios, thank your heavens because it can get pretty embarrassing. Thankfully, because these aren't full stalls, you won't be walking out all filthy and embarrassed. A friend or even a stranger can easily pass you one through the stalls.
