Needed to fill up my rental car with gas before returning it. Attendant would not allow me to fill up the tank and then charge the credit card. She insisted that I give her an amount to charge on the card first and then she would charge the credit card. Obviously there is no way I could know the exact amount and therefore was unable to purchase gas at this location.
Drove down the road several blocks to a gas station that had joined the 21st century and had no issues topping off the rental car.
