Well of all the blanket blank blank!

I have received enough half full, almost empty, tanks that I always make them put a regulator on one before they load it in my truck. I figure if I am paying for a full tank, I should get a full tank. Got in a debate with the dock hand about pressure amounts in a tank just a couple of weeks ago. He wanted to try to tell me the tanks where sold by cuft the tanks hold and not by the amount of pressure in the tank. Now I realize a xxcuft tank will hold xxcuft of gas, but there will be a lot more cuft of gas in a tank at 250psi than there is in a tank with only 150psi. And why does one oxy tank have 1800psi and the other 2200psi. for the same size tank. After some debate, I made him load the tank with the most pressure and let it go at that.

That kid sounds like the tale I heard about a guy installing garage door openers. The homeowner had a 1/2 HP opener that wasn't working and the installer said "Well the reason it isn't working is because you need a 1/3 HP motor. Trying to explain that 1/2 is greater than 1/3 just didn't work because he said 3 is bigger than 2 so it is the largest. This is the math they are teaching to our kids today.
The welding supply kid just couldn't relate PSI to cubic feet of a gas possibly because his boss just said that we sell by cubic feet, this bottle holds xx cubic feet and didn't explain that it is pressure related.

Gary, this wasnt a kid, and he has been in the welding business for years. He was a welder when I first met him back in the 70's. Heck of a good welder, I've known him for a long time. Some folks just cant comprehend I guess.
