Alamo at San Francisco Airport has many counters, the speed was acceptable.

The service personnel kept trying to sell me extras and their English was terrible. I had to confirm multiple times, and they were very impatient.

I returned the car on time in the morning and had my boarding pass at 8:07 AM, but later they charged me more than $23, claiming I returned the car late in the afternoon at 6 PM. I wasn't even in the US at that time. Did your employees use the car and charge it to me? There's been no further response. Very disappointed!

QEEQ provides fast and convenient service.

Overall it's quite good, with a competitive price. They didn't push any extra items when picking up the car. Since I was planning a road trip, I opted for roadside assistance at $5 per day, which is reasonable. Alamo is quite friendly about opting out of certain charges, like crossing the Golden Gate Bridge (north to south); if you pay online yourself, you can automatically opt-out of Alamo’s charges without contacting them. Picking up a car at San Francisco airport was quite intense, it felt like there were more people than cars, and you had to grab one as soon as it appeared.
