When we arrived at the airport car rental station, we were told that the car would be picked up at Terminal 1, but it was temporarily changed to Terminal 2. We dragged our large suitcase to Terminal 2 only to find that if we wanted to buy full insurance here, we would have to pay an additional tax of nearly 300 RMB. The service staff seemed to be from India or Sri Lanka, intentionally speaking English with a very heavy accent, making it nearly impossible to understand. Luckily, there was a girl who spoke Chinese to help us out; she worked there as well. She told us that the Hertz staff member was doing this on purpose, and they usually don't speak this way. It was really infuriating. When returning the car, we handed over the key, and the staff immediately said it was OK. We felt that someone should check the car condition, but no one did. Concerned that any scratches could be blamed on us later, we went back to the parking lot to take pictures of the car. Now that it's been more than two months since we returned the car, and we haven't received any fines or charges, it seems everything is fine.
