Rip off's my you don't know about fuel tanks. Unfortunately we called Arizona Propane of Glendale and scheduled a visit. On that day to my disappointment my wife ran inside to my office and said the man only put enough propane in the tank for the level meter to display 10%. Not Rocket Science . .100 gallon tank 10% = 10 gallons, But no. The man driving the truck told my wife she owed him $160 for 50 gallons, and said the meter did not read actual volume but liquid level. The said his truck meter was broken so we could not get a 50 gallon receipt. Basically trying to confuse my wife and short change her 40 gallons of fuel. Yes this really happened. After talking with my wife we called the owner and said if he could not measure the fuel provided then we would not pay him. Out of the blue the truck's equipment is working fine and the tech pumps 50 gal of propane into our tank and provides a receipt. Wow . . Buyer beware they will try and short you on fuel and charge you for 5 Times what they actually provided, that's bad . . really bad. They should be assumed of their professionalism and morality in general.
