The service at the Dallas Airport branch is mediocre. My order was for a full tank, but the car I received had an empty tank. There were no other cars to swap, so I wasted a lot of time. In the end, we had to agree on returning the car with an empty tank, but I couldn't use up all the fuel precisely. When I returned the car, there was still a quarter tank left. Pay attention to your order, as they might add insurance without you noticing at the reception. I found out when returning the car, but fortunately, I got my money back. Overall, the service at this branch is quite average.
