The process of picking up the car at the airport counter was very slow. During both pickup and return, I noticed that Budget added unauthorized charges to the bill. When picking up the car, they didn't ask if I wanted to refuel it myself and instead chose the option for the rental company to fill the tank, which cost an extra 56 euros. I had to request a new bill after noticing this. When returning the car, I found an extra driver fee on the bill even though I was the only one with a driver's license and my friend didn't have one, so it's impossible for there to be an extra driver. Even if I needed an additional driver, they would have to provide their license at pickup. These issues made me feel that this rental company is not very trustworthy and always looking to overcharge.
