I only inquired about whether insurance was needed and whether the car should be returned with a full tank, other than that they didn't bother me with unnecessary details, which was nice. As for the car model, the staff selects it for you (with company A, you can choose a car of the same specifications in the parking area yourself). If you have specific model requirements, you might want to ask when they confirm your order. I used to always go with company A because they had an automated pickup machine which saved dealing with staff. This time, I found out that the automated machine was shut down, and I had to wait in line to talk to the staff.

My total rental cost was $771. At San Francisco Airport, the service staff gave me a bill for $1160, claiming it was for a vehicle upgrade. When I asked if it was the upgrade fee, they said it was a deposit. There were a lot of people in line, so I didn't check carefully. Later, I found out that there is no deposit for car rentals in the US.

Very, very poor. Given the wrong car pick-up location and vehicle, had to queue at the counter again. Clearly supposed to get a full tank of gas, but intentionally given only half a tank and charged for a full tank.

Pretty good, but the front desk staff seemed a bit tired and slow with their tasks.

I don't understand why the actual rental price is over 20% higher than the online price. Are the taxes really that high?
