A hooker.
I made a deal on Craigslist to meet a guy to buy Record of Lodoss War on Dreamcast. Was supposed to meet him in a hotel parking lot in town. Waited for about 20 minutes, guy never showed, I give up. On my way out, I see a woman standing out front, so I pull up and ask her, "Are you waiting for someone?" She replies, "Depends, are you looking for a date?" Took a second, then it clicked in my head. I'm like, "Ohhhh, no, I'm not. Sorry." Then went home to my wife. Never did get that game until a few years later from someone else. (Grindiest game I've ever played. Sucked.)
