Thank you to the family who gave me petrol on the Son Tra road

At sunset my motorbike ran out of fuel at the top of a hill on the Son Tra Peninsula road. A family on a scooter, a plastic bottle of petrol tied to the back, stopped, filled my tank halfway and would not take money. They told me where the next station was and rode off with the empty bottle bumping against the frame. I did not catch their names. I keep a bottle under my seat now. I have not needed it. I think of it as a debt.
