This is a great thread!

I had driven to a convenience store one day, and I must have run over something sharp on the road getting there...one of my tires was flat, flat, flat when I got to the store. A man pulled up next to me and asked if he could help. We aired up the tire at the air pump in the parking lot, and although we could see it going flat again, he thought it would probably hold air long enough to get me to the tire store.

Then, instead of going into the convenience store as he had originally planned, he actually followed me to the tire store in case my tire didn't hold air long enough to get me there. It was close, but we hit green lights the entire way and made it.

He refused my offer of money to pay for his lunch or dinner. He just smiled, said he was glad to help, and drove away. Still makes me smile when I think about this.
