Ewwww.... I shudder at the thought.
One time I went into a bathroom stall, and as I pulled my pants down, some change fell out of my pockets. It was less than $1, so I wasn't real worried about bathroom floor change at that point, but all of a sudden 2 hands from the next stall darted under the stall and started grabbing it!
I screamed "WTF ARE YOU DOING YOU FREAK!?"
And they threw open their door and ran outta there.
All for less than a buck.
I hope they caught some nasty shyt from those bathroom floor coins.
