The tire had a leak midway, but I quickly found a store and got a new car.

The counter staff was very friendly. When I picked up the car and had questions, the on-site staff came to help immediately.

I waited in line for twenty minutes. At the counter, I wasn't informed about the extra insurance they added. Later, I noticed unexpected charges and realized they had added all the extra insurances without telling me. The staff at Avis never mentioned it to me.

Customer service at San Francisco airport was indifferent.

The San Francisco airport location was extremely busy; we waited for almost an hour. The staff were inefficient, and I saw one woman chatting away with a customer, completely ignoring the line behind. Although the rental cost through zuzuche was 1250 USD, we added insurance for about 90 USD, making the final bill 1420 USD. The staff tried to add various insurances, and you have to negotiate yourself. It's quite troublesome, especially if your English is not good.
