I am on call for the propane company I work for this weekend. I get 2 calls for "no gas pressure" in one of the trailer parks we supply. Each tank supplies between 4-6 trailers, each of which have a meter and shut off valve. Upon arrival at the tank in question I see that it has been turned off, cutting the supply to 4 trailers. I began knocking on doors to explain the issue and re-light everyones pilot lights. The first house has broken pieces of gas pipe in the front yard so I deduced that they might be the culprit who turned off the tank. I knock on the door and am greeted by a rather large individual who explains to me that he doesn't need the gas company on his property, that he has handled the problem and turned off his tank so I can get off his property. I explained that it was our tank and that he had shut off the entire street's gas and that if he touched the tank again I would be calling the police. I shut his gas off at his meter, turned the tank back on, and proceeded to light everyone else's pilot lights so they could have heat. Then I took pictures of the tank and the damage he had done at which point he came out and started talking tough and when I explained that I was just doing my job he accused me of colluding with his neighbors against him, being friends with his neighbor and being out at the park visiting him and that I wasn't working and didn't have the authority to touch his property, and having smelled alcohol on my breath. It's not enough that the dumbass shuts off the tank and all his neighbors, makes me get out of bed to go fix his stupidity which took almost 3 hours, but them on top of it all he starts threatening me. I am a fairly calm individual but I was closer to violence tonight than I have been in years.
