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.
