Ever been scammed in a truckstop, rest area, dock, etc...?
I stopped in Richmond, VA at a Hardy's off I-95 that had truck parking. A woman with 2 small children pulled up next to me in a car. She got out holding an official looking paper and explained she just came from the doctor and needed to get some medicine for her kid but she was short of cash. Mr "Nice Guy" here quickly handed her $20 and she was off like the wind.
The following day I was talking to my mom on the phone when she brought up a scam she heard about on the news about the very thing that happened to me. Oh well, I figure if I was scammed the guilt is on the woman who scammed me and in the big picture of things I still get "credit" for helping someone.
