Rented at car for less than 24 hours and drove less than 75 miles. I returned the car after hours before they opened. I was told this was no problem. When I got the bill they charged me an extra $13. Then I wrote them they said if you drive less than 75 miles and do not give them a gas receipt they charge you a refueling charge. They never told me they would need a receipt and if you turned the car on you could see it had been refueled. I have rented from other car companys at this same airport and never had this problem. I will not be renting from Budget Rent a Car at Montgomery Alabama airport again.
