That's just nasty

So today I go to the bathroom at work to wash my face and take a whiz right?? Y is it the second after the door closes behind me I hear someone dropping some major business in one of the stalls!?! I just left...this is isn't the first time this has happened, but it still confuses me. Why don't you wait til you get home for #2?? Or if you really have to go, hold that thing when someone walks in!!!. It's even worse if it happens while your peeing and they come out while you're washing your hands...now you've seen their face and you can never handle business with that person the same way again. Folks, just save it for your personal toilet...please, for the sake of the rest of us.
