They patiently helped me resolve the car issue for half an hour.

Extremely inefficient. It took over an hour from queuing to get the car, and the car given had not undergone a safety check. The rearview mirror was broken, but they still tried to hand over the car to me. After complaining, I waited another 1.5 hours to get a new car. The replacement car was severely damaged all around the body, and the gas tank was only 80% full. I have been renting cars in Europe for over 10 years, and this is the first time I have encountered such a situation. It is truly disappointing!

Note that Thrifty's operations are actually handled by the Hertz counter. There are a lot of people, and you need to take a number and wait to be called. There's a ticket machine at the entrance where you enter your last name, and it will show up on the screen. Just wait for your number to be called.

Waited nearly one hour to pick up the car

This was the worst car hire experience ever! Did not got convertible as reserved. Instead a scratched hatchback after over half an hour wait. And even No apologies from Hertz. Not to speak of any compensations as I have got from other companies even from long queuing times.
