Gas company is ran by thieves (CEO and customer service representative to be exact). Once you buy gas, if you need to return for whatever reason they do not charge a return fee- instead they charge you the full amount and only refund you half of what you paid. They will also steal the gas you already had in the tank before they filled it. Customer service will make you a deal and then go back on it when it comes to them screwing you out of money. Use Thompson gas instead! Trust me!
