I know this is an ancient post, but how the hell could you not have said something?? Like "DUDE, WHY ARE YOU SHITTING ONTO THE FLOOR??? Are you a fucking ANIMAL?? WHY aren't you using the toilet directly? That fucking reeks! WHY do you think we have toilets with water? it's to mask that fucking stench of shit!! what's WRONG with you, and who is your boss??"
I am not an aggressive person normally but that kind of shit (lol) would set me off instantly. I wouldn't let anyone get away with that shit (moar lol) in that case.
GodBear DAMN.
