Reception at the counter was unfriendly and impatient in answering questions

Very good, the staff were friendly.

The car rental company wasn't very helpful. When the tire had a leak on the highway, we were stuck for a long time because there was no Chinese-speaking customer service. They didn't offer any constructive suggestions. Finally, I suggested swapping the car at the nearest location, and only then did they agree. Communication was really difficult, but the replacement car was fine.

Acceptable

The staff at the store were dedicated, responsible, and enthusiastic. They provided detailed information about the car condition, vehicle usage, breakdown alerts, and driving tips in the US. Renting a car in the US is very common, but the rental process itself is quite interesting and enjoyable!
