I returned the car on the 16th at the rental store. The fuel level was 7/8 when I rented it. However, since we were in a hurry to catch a bus to Seattle, the fuel level was 1/2 when I returned it, not fully refueled. Although we refueled the car once during our rental period and it cost only $24 to fill the tank, the rental company still charged me nearly $50 for fuel. When I requested to refuel the car and return it, they did not allow it. As we had a lot of luggage, taking public transport or taxis was inconvenient, so we hoped the store could give us a lift, which was only about a ten-minute journey, but they refused. This experience has given us great fear and concern about renting cars and handling related procedures abroad. If even reputable companies like Hertz provide such service, who would dare to rent cars for self-driving tours abroad?! Additionally, to facilitate domestic travelers in handling rental procedures abroad, foreign stores should provide process instructions and other information helpful to Chinese travelers.
