My daughter and I had gone to a local fast food restaurant to pick up dinner for the five of us. When we go to the window the cashier asked if we remembered seeing the dark colored suv about 4 cars in front of us? Of course we didn't, but they had paid for the five cars behind them - we were the last one in the group they had paid. I was absolutely floored. So we paid for the car behind us. And I continue to do that when I have the extra funds - pay for the car behind me.
