The Budget SFO branch had a long queue, but one staff member (an elderly Asian man) was working very slowly, taking over 30 minutes with one customer while 20 people waited behind. This was very frustrating. The young man who assisted me was quite fast though.

I only inquired about whether insurance was needed and whether the car should be returned with a full tank, other than that they didn't bother me with unnecessary details, which was nice. As for the car model, the staff selects it for you (with company A, you can choose a car of the same specifications in the parking area yourself). If you have specific model requirements, you might want to ask when they confirm your order. I used to always go with company A because they had an automated pickup machine which saved dealing with staff. This time, I found out that the automated machine was shut down, and I had to wait in line to talk to the staff.

The car was very dirty inside, it was quite disgusting. There was a gap between the front and rear windows

Drop of was a nightmare. I was not able to find the point. Therefore I missed the evening. However the agent said that she were there in the office. We confused about where to part, an we not even checked the office as we though it is close. It was not, but we did not reach the office because we did not find the drop off parking lot.
