“Pay it forward”
I do that (both sides) when I can. One time a young lady ran out of gas in front of my house and I gave her what I had in the gas can, $10 for the station up the street, and a “pay it forward”.
She refused in the nicest way. I got a card a month later with $11 and a note explaining that “In my religion, debts are paid back with plus one.” Ya’ learn something new every day...
(If you were gonna ask; hindu.)
Hindu huh? Saves from being born a cockroach in the next life. I try. But I have my days.
