No Chinese service, unclear about which fuel to use, and how to pay for tolls

The service wasn't particularly good or bad. However, the wait time was very long because there were a lot of people renting cars. Despite having over ten counters open, I still waited for about 45 minutes.

Good, you can pick up the car very early in the morning.

Counter staffs was helpful and give good advises etc

San Francisco pick up was very lengthy. We waited over an hour to be served due to high demand, low number of staff and low number of vehicles available. When we were eventually served we were told our booking was not for that location despite my reservation stating it was. I specifically chose that location being within walking distance of our hotel. We were told the car was the other side of San Francisco so ended up getting a taxi there. When we eventually arrived we were dealt with very quickly though. There is obviously a problem with the on line booking system in addition to organisation at the local branch in San Francisco.
