I guess if it sounds to good to be true, it probably is.
Along this same line.
When I was very young we went to a Cincinnati Reds baseball game. At that time the Reds stadium was in a bad part of town. The lot was full so we parked in a field across the street. This little black kid charged us a dollar to park there. Of course, we knew he wasn't working for the team nor did he own the lot. However, if you didn't pay him it would be hard driving home without tires.
