Got to the counter at CVG. With a reservation. They got my credit card, all well, till they detected that I am Mexican. The clerk goes inside the office, a manager comes out and he tells me that they can't rent me the car. Because my license is no good. They had not even looked at it. I had to go to Alamo and rent a big SUV that i did not need. It took me 10 mins to do so. Shame on you Sixt!
