If you don't want to queue or deal with the counter staff and avoid insurance offers, Alamo has a row of self-service machines in the rental lobby. Simply input your reservation number, driver's license number, swipe your credit card for the deposit, select 'no' for the other options, and the rental document will be printed out.

Not many people, barely had to wait in line, picking up the car was very smooth.

They only symbolically pushed the GPS option during pick-up, the rest was hard to understand. I went to the designated location to get the car. During return, they only checked the fuel gauge and took the keys.

Too few airport shuttle buses to pick up and drop off customers. Waited 15 minutes at Los Angeles airport for the bus to arrive, while other companies had more buses. After returning the car in San Francisco, there was no shuttle bus available at all.

There is a shuttle bus, and it takes about 15 minutes to get there.
