andrew, be happy you don't have my roommate. We live in a suite and he has a similar problem in addition to the facts that he doesn't know how to use a plunger (highly advanced technology) or change a toilet paper roll (incredibly advanced technology). *sigh* You could always leave one of those tongue-in-cheek signs that resturants sometimes have, such as "We Aim To Please. Please Aim." Or something along those lines.
