I am sorry but worst experience, I booked a car with Thrifty car rental but they asked to pick it up at Dollar Rent a Car (may be they are working together). The customer service over there is very bad, they were unhappy that I came to pick up the car booked from Thrifty. The agent started criticizing about picking the car at this location. I gave him my US drivers license but he also asked me my international drivers license and I gave it to him. After a while he started saying that the system is not accepting and he asked me to call the booking company and cancel it. It was midnight and he made us (I was with my wife and mother-in-law)to wait for more than 2 hours. Finally I had to cancel my existing reservation and book another one with Dollar for twice the price that I had paid before. He looks like an Indian and his costumer service was very bad and he was rude and impatient all the time.
