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.

We chose a service at the store that allows returning the car without a full tank, which saves time. However, we found out that the remaining fuel is non-refundable. We can accept this, but it would be better if it was mentioned online.
