I had a problem -- my basement had flooded and the pilot light on the hot water heater went out. I was hesitant to relight it myself and called TBros for advice. they told me how to light it and then, to my amazement, about 1/2 hour later i got a call from one of their plumbers asking whether that had worked and whether I still needed them to come out! amazing. And they didn't get a dollar from me for this -- it was excellent service, especially considering they had received no payment from me.
