What goes around comes around

A suggested summary for What Goes Around Comes Around

An old lady was stranded on the side of a road with a flat tyre one day. She had
waited for an hour before Bryan Anderson arrived to offer his help. When the flat tyre was replaced, she offered to reward Bryan. Bryan politely declined her offer, claiming that he had helped because he was brought up to help others in need and did not expect any monetary returns.

Before they parted, Bryan told the old lady that she could repay him by passing the kindness to someone in need.

On her way home, the old lady drove to a dingy café to grab a bite. At the restaurant, she was treated warmly by a heavily pregnant waitress. Deeply touched by the waitress' spirit of giving, she gave the waitress a fat change, together with four $100 bills under the napkin.

The waitress did not have the time to return the money to the old lady but she would not forget the words written on the napkin, urging her to carry on the chain of love. Little did she know that the greatest thing that had happened to her was a result of her husband's kindness to a stranger.
