They try to sell insurance.

The Asian-looking male receptionist tried to add over a hundred dollars of unnecessary insurance without explanation and asked me to click 'agree.' Luckily, I noticed this by following the guidelines from the car rental website. When I asked him to change it, he added another $60 or so for GPS without any explanation again. I had to emphasize that I had already purchased and prepaid for everything I needed before he finally corrected it to zero. This is a typical case of taking advantage of Chinese customers. You can upsell, but you must explain it—this is deceptive.

Long wait time

Very polite, but insists on adding extra services.

The queue time for picking up the car was a bit long, about half an hour.
