One day I went out to pump the gas for someone in a very nice SUV. When I went to the driver's side window all I saw was a a well manicured hand holding a $100 bill. The dark tinted windows were barely cracked so that I could hear the lady tell me to give her $20 worth of gas. I pumped the gas and I went inside to get the change and when I turned around to go outside to give them their change, the SUV was gone!
I went outside to look both ways and I didn't see the vehicle. I walked over to look at the parking lot next door because many of the customers would go over there after they got gas. I saw a black SUV in the parking lot but I wasn't sure that it was them. I called the manager of the store next door (I worked there also) and I asked him to track down the owner of the black SUV in the parking lot and see if they accidentally left me their change! He found them but he said they told him that it wasn't them.
It was then I started to realize that they had left me the money on purpose. I was happy on the one hand but on the other hand, I was worried that they would realize that they had made a mistake and could still come back. I didn't spend any of the money for 3 days - just in case they did come back for it. Even then I bought groceries with the money, so that if they did come back I would just be able to repay them out of my pocket.
A couple of days before Christmas I decided that they weren't coming back. I bought myself a little something and I bought presents for my nieces and nephews that I wouldn't have been able to afford otherwise!
Because of the mystery Santa in the SUV, I had a very Merry Christmas that year.
