It does feel real good.
I had a leak to repair under a house today and could not get over to the leak.
I told my client and he said he could crawl over and fix it himself, I offered to sell the parts to him and he agreed. I left, and he called needing some advice, I returned and coached him through the repair, I even made a trip to the supply house for him. He offered to pay me for my time and ended up paying me more than what I would have charged had I repaired it myself. How's that for a satisfied client?
Oh, and mine was not in a heated shop.
