The problem you're describing a solution to doesn't exist. Gas included in the rental -- Each car has a fleet card that can be used to fill up at most any gas station. With ZipCar, the rule is you should never leave a car with less than 1/4 tank of gas, and if you do, you're hit with a $20 fee. I think the GP is upset he had to spend time filling the tank back up.
