Guy calls me up about my ad for a computer. He says he needs a simple one and needs it badly. I have it posted for $250 and we agree over the phone for $200 and he says he'll take it and will definitely call me back when I get off work. I get home after work and start getting the pc ready for this guy but he doesn't call. Fine. I then put the pc back into storage. Two days later the same guy calls back saying he's still interested. I tell him to call back when I get off at 4:30 and he agrees. Surprise surprise, 4:30 comes and no call.
