When we picked up the car in San Francisco, we waited in line for half an hour, and there was no self-service option, which is not as good as Alamo. The receptionist, who seemed to be Chinese, spoke English the entire time and was very polite with a constant smile, but we felt he was a bit deceitful. Despite having already purchased full coverage insurance from the rental website, he forced us to buy an additional $50 insurance without explaining it properly. He simply mentioned that if anything happens, we could call this number for assistance, and we agreed. He then presented us with a bill that was $52 more than our reservation. We almost fell for it. When I asked for clarification, he finally backed down. We even showed him our reservation which clearly stated in English that we already had all the necessary insurance and didn't need any extra coverage.
