A relative had a 1/2" galvanized pipe that was capped coming out of the ground next to his house. He's about 80, and had been born in the house, and he didn't remember it ever having been hooked up to anything. Well, he was mowing with a rider mower one day, and banged the pipe. It broke at ground level, and it was obvious it was gas.
So, he called the gas company. They told him it would be a while before they could get to it, but that they tell everyone to just light the gas! He told them that it was less than 4" from the house, and they still said their procedure was to tell the owner to light it. Since he was a fire comissioner, he didn't think burning his house down would look good. So, he remembered that gas is not under a lot of pressure, and whittled a plug out of a piece of soft pine, and tapped it in there gently. That sealed it until the gas company came out THE NEXT DAY. How's that for service?
