A couple of years ago I was doing a partial rewire on a Vicrotian house and the GC was removing some old gas heaters.

I saw him tackle the first one by stopping the end of the pipe, having his assistant turn the gas on, and putting his ear to the end to "listen" for a leak. As I saw him take a lighter from his pocket and strike it I decided to beat a hasty retreat, making excuses that I'd run out of something and had to go back to the supply house.

I went and had brunch in town and figured I'd come back later..... If the place was still standing! [Linked Image]
