This conversation gave us both a laugh.

HO: My air conditioner isn't working. My sister's husband's uncle said that it probably needs freon. You do air conditioning right?

Benncool: Yes we do air conditioning.

HO: I don't mean like putting in ductwork. Like do you have gauges and the hoses.

Benncool: Yes we have all of that.

HO: So, then, you do know how to charge? (he was thinking refrigerant)

Benncool: Yes sir, We, CERTIANLY DO know how to "charge". I have a pencil and an adding machine. (I was thinking money)
