They insisted on charging me a 500 cleaning fee for smoking. There was no prior communication, and the inspector just deducted the fee directly. This is very frustrating. Customer service is now involved to handle it.

The service attitude was okay, but because I did not purchase the additional insurance, the car provided was in poor condition. It was a red Kia with no power to climb hills, and the engine was unstable, functioning inconsistently. In the signal-less mountains, it almost stalled, scaring me half to death. During the 9 days of self-driving in the USA, I was constantly on edge, worried the car would break down in the middle of nowhere.

Not very satisfied

Arrogant attitude, insisted on extra charges

There were quite a few people, but fortunately, the car rental service counters at San Francisco Airport are numerous. A short wait was all it took.
