That guy who gave you his chip gave you the most precious thing he had. It's worth more than a several thousand dollar check from a millionaire. The circle is unbroken. What comes around goes around bro. And if people don't reciprocate, it does one good to give anyway. There's no way I would be alive today if people hadn't extended the hand of kindness to me. Sure, some people (strangers) have hurt me, but even more strangers have helped me.
