They thought I didn't understand English and selected an additional paid insurance for me. I later found out and had it corrected. They kept trying to sell me insurance and other unnecessary services. Returning the car was convenient.

The staff were very helpful, providing guides and assistance for online self-service car pickup.

Picking up the car was quite convenient, located right across from the Hilton Union Square. However, Thrifty and Dollar have merged, so the line was somewhat long. But there were plenty of staff, so the queue moved rather quickly. Returning the car was even more convenient. We returned it in Las Vegas at a dedicated car rental center. Just follow the signs all the way in. You don't need to wash the car; just return it with a full tank of gas. There are many gas stations nearby, and the prices are fairly cheap. The car return location is not inside the airport, so you'll need to take a free shuttle bus to the airport. It's very convenient and takes about 10 minutes to get there. The driver is very nice and helps with the luggage, so you can give a small tip.

I had previously rented a car at Washington Dulles Airport and experienced Dollar's aggressive upselling. So this time, I deliberately avoided Dollar and chose Thrifty, not knowing they are the same company. The attendant I encountered this time was even worse than the last one. Initially, the paperwork was smooth, but then they started pushing all sorts of insurance and toll passes, asking me to pay an additional 300 dollars, almost the cost of my 10-day rental. I repeatedly said I didn't need them, but he kept pushing. A Chinese friend behind me in line couldn't stand it anymore and told him I had already bought the necessary insurance when booking, only then did he stop. However, his attitude changed, and he angrily tossed the documents to me, directing me to the C-class car area. When I got to the parking lot, I found their so-called C-class cars were small vehicles like Hyundai Accents, whereas I had booked a compact car. I went back to negotiate, but he insisted that the car I booked was of that class. I called QEEQ customer service for help, but they couldn't resolve it either. As it was getting late, I had no option but to drive away in frustration. Later, I noticed the rental agreement clearly stated the car class as 'B', it felt like deliberate retaliation! This was the worst of all my international car rental experiences and I have never encountered such a malicious person abroad!

The staff the day before of my pick up was rude, I want to pick up my car the day before paying the difference and they say that is not possible, because they didn't have cars available even when they have a big sign that said "cars available". I had to return the next day.

Very easy to book my car and excellent price.
