the point is people who do not return the car full (filled up within 3 miles of the return location) should be charged for gas, if you get caught by the CSR on return, take your lumps. I tired of putting in 3.6 gallons in the car for a car I drove for 30 miles. I show the return agent the receipt and get credited. It's like you damage the car, return it, not get caught, and the next renter is in a hurry, takes the car, gets blamed for the damage. Don't blame the next guy, take responsibility.
