The American rental process and efficiency are quite high, but due to peak times, the staff were busy selling insurance, resulting in a wait time of over an hour. We arrived at 4:30 PM and got the car close to 7 PM, which was quite exaggerated. Additionally, the pickup process was a bit chaotic as the car model differed from the order, and it wasn't clear if the car was in the same class. The external staff were few and couldn't provide a clear explanation. The car condition was just average; you have to pick one yourself. The return process was efficient. We arrived early, afraid of delays, but the return process was very fast.
