I was talking to a friend of mine the other day, who is a kick-ass professional plumber. He used to freelance but the company he works for now won't technically let him do any moonlighting. Anyhow, a friend of his, who has a teenager with cancer (and lots of medical bills) had a water heater go out on him. He called Gary up in tears, and Gary went in his own truck on his own time and fixed it for nothing. The guy wanted to pay him something, so he gave Gary a really nice leather belt. But Gary told him not to worry about the bill.
