I was approached at a gas station with a similar story. I figured it was most likely a scam, but I thought "maybe not" and, feeling generous, I bought the guy a tank of gas using my credit card on his pump, which was the same pump as mine but opposite side. Then I filled up my car, and later reviewed my charges on that card and realized that my fill-up was never charged. Which is really weird because modern automatic pumps will not dispense fuel without validating the credit card. Can't explain it. I just chalk it up to karma.
