The guy who acts like you're stupid because you don't understand his special area of expertise.
Just went through this installing some propane powered equipment. I don't know dick about propane beyond hooking up the cylinders for grills and stuff.
The equipment got delivered except for the propane hook up, and the guy was coming down to do training, so this was all over the phone. He told me to order two hundred pound tanks. I do that, then he told me to get the equipment to hook the tanks together and run them into the common connection.
"Oh, hell yes you need to get a regulator. Also you need a gauge. Just get a common hookup."
So I start asking questions about the regulator. How much pressure does it need to be able to handle? Dittos for the gauge. What thread do these systems use? I tell him I don't know anything about these types of hookups and that's why we're paying them $67,000 for this equipment is because they're supposed to be the experts. Do the large tanks have a different type connection from the small tanks? What diameter pipe do I need? Should I teflon tape the connections?
Guy acted like I was stupid cause I didn't come out of my mother's womb understanding how to build a propane manifold out of parts from Home Depot.
Oh, and when he shows up, he's like, "these tanks are too small."
"You said two hundred pound tanks."
"Oh, I meant two hundred gallon tanks."
I tell him, "Propane's sold by the pound and the gallon. There's a lot of difference between a pound and a gallon."
