I rented the car in my name not knowing that means I am principle driver to Thrifty. My husband does the driving so he was added when we got to Phoenix. Not once did the agent say that to do this it was another 13. Per day plus a 48. Charge to add. My ticket he gave us does not indicate these charges or I would have questioned immediately. He then asked us to top up upon return saying that gas prices around Phoenix airport were around 4.50 a gallon. Not knowing what prices were and Thrifty price was 3.10 so thought it was a bargain. It was only 2.95 we found out so topped up before dropped off. They charged us 49. Extra. Eventually got that removed since they did see it was full but if did not question the charge it would have stayed. They insist they cannot remove the extra driver charge. I believe this company unethical and do not explain charges they add after the fact.
