I pulled up to an ATM in a strange town once to get some cash for gas.
There was an elderly man in a car at the ATM, and it was obvious that he was having problems with the machine. I just sat and waited for him to figure it out and go.
When I pulled up to the machine there was $100.00 dollars in the slot and a card sticking out.
I grabbed that cash and that card and drove like a maniac to catch him. Fortunately he had a distinctive car. He looked at me when I pulled up beside him at the stoplight, and then drove off as fast as he could.
I caught him again at the next light and held up the cash and the card. He pulled over and stopped and I explained myself.
He started crying and told me his wife had been taken to a hospital a long distance from where we were, and that he realized he would need gas for the trip, so he lost the ambulance when he stopped, and then the machine didn't give him the money or the card. He figured his wife would understand and that if he had to he could sleep in his car until he could call the bank and get it straightened out.
He tried to give me $50.00. I refused. I told him I would like to think someone would have done it if it was my grandfather. We both went our separate ways after he gave me a hug.
I figure that it was worth some brownie points on something inconsiderate I have done in the past.
