When picking up the car, the gas tank wasn't full, and I wasted an hour waiting.

At San Francisco International Airport, all the rental companies are in one area and connected by a tram, which is very convenient. They'll try to upsell you to a higher class vehicle (telling me there's a half-price upgrade promotion) and add insurance. Because of the language barrier, my contract included an extra insurance. I immediately questioned it, showed my QEEQ order, and told them 'zero, zero'. They said my insurance didn't cover emergency rescue, and I declined it. They later canceled it and told me 'don't worry'. Importantly, you don't need to print out the pickup form; just tell them the pickup confirmation number. Printing a document abroad can be troublesome and usually requires self-service credit card payments. I once spent $17 to print a pickup form, but it became invalid later due to rebooking! I hope QEEQ's customer service advises customers not to worry about printing.

Both renting and returning the car with Alamo were very convenient

Standard service.

The service of Alamo car rental company is good, no issues. However, I raised the following objections during the contract signing, which put me in a very passive position!
