Actually this hapened to me twice.  Someone asked me for $5 so he could buy gas to go home. He ran out of gas on highway and has no money to buy gas.  He asked me while I was in a gas station filling up my car.  I gave him $5 to help him out and totally forgot about it!

Several months later .....  someone asked me for $5 so he could buy gas to go home. He ran out of gas on highway and has no money to buy gas.  He asked me while I was in a gas station filling up my car.  I gave him $5.00 to help him out and was thinking back in my head that I had heard similar story before, but could not recall right away.

It was only a few hours later, I realized it was the same person in the same gas station telling me the same story asking for same amount of money!  When I remembered the previous incident, I felt totally dumbfounded!  Now it appears these kinds of nuts are everywhere!
