They try to sell insurance.

We waited for almost 2 hours to rent the car, even though there weren't too many people.

At the BUDGET counter at Seattle International Airport, I booked a Ford Expedition, but they didn't have the car. A female staff member at the counter asked us to wait, saying she needed to consult the manager for a replacement. We waited for 45 minutes. When we finally got to the parking lot, the car she gave us couldn't fit our luggage. I specifically booked the largest car, and she seemed unsure if the car would fit both us and our luggage. She didn't even offer a discount for giving us a smaller car. Luckily, the parking lot staff were kind and helped us pick a Toyota Sienna. Although the Sienna's performance doesn't match the Ford, it was a hassle to finally get a car at noon after arriving at 9 AM.

Everything else was excellent, the only issue was because it was raining. The store manager suggested we upgrade the car from the convertible we initially booked to a Jeep SUV. However, when we got to the parking lot, we saw the Jeep was also a soft-top and quite small. We went back to the store to request a change. Since the pre-authorization was already done, the manager tried to say there weren't any cars like the one we originally booked and suggested another upgrade. I mentioned I saw plenty of the original cars in the parking lot, but he insisted they were all reserved. Finally, I said if we didn't get the car we originally booked, we wouldn't rent from them. Only then, reluctantly, did he agree to give us the car we originally booked. Despite this, everything else was great; the rental point is conveniently located from the airport, return was quick, and the car was in good condition. However, it seems rental companies tend to mislead Chinese customers into upgrading. Hopefully, this can be improved in the future.

Budget rented us a car with 3/8 tank of gas. We ask that be noted and they did. When we returned the car had over a half tank. They charged us for refueling and the gas itself over $120. We are of course disputing that overcharge with them.
