I had a similar experience 10 years ago when my then-girlfriend and I moved into our first apartment together. We figured it was some drunk tool who knew the last resident and ignored it, as hard as it was to do so. The second time was even more difficult, the third time was on a Sunday morning: I jumped out of bed wearing only my skivvies, thoroughly pissed off, whipped open the door and screamed ""WHAT?!?!?!?!?!?" in the face of the two losers standing there. The guy, it was a scabby-looking couple, nervously asked for some dude, to which I replied " **** NO, HE DOESN'T LIVE HERE!!!" and slammed the door in their face so hard the walls shook. Never had that problem again.
