Yet another embarrassing moment

All the conference rooms at my new job are named after cities (Santiago, Miami, etc.), and are in alphabetical order. Helpful, right? Not if you forget the city you're supposed to be in. I had a meeting scheduled yesterday with two guys I've never met, in the Rome room. So at 2:00 I walked over and there were two guys in the room, along with a lady. I introduced myself and started to sit down, when the lady - also the HR director, apparently - told me they were in the middle of an interview. I turned bright red and stammered some sort of "Wrong room! AACK!" as I backed out of there as quickly as possible. Turns out, my meeting was in RIO. Son of a.
