The rental company will ask if you need additional options when picking up the car on site. Just say no if you don't need any.

The pick up agent tried to fool me that all gas stations would be empty by the time I return the car to convince me to purchase the gas from them.

Like: In terminal location n/a

Like: Great value, nice vehicles and friendly staff!
Dislike: Slightly different vehicle than rented, although most might say an upgrade. I just didn't know about it until going to parking lot to get vehicle.

Like: In the parking garage, there was no wait and we were able to get the keys immediately and start our vacation!
Dislike: The wait to pick up the car in the terminal was long. The person waiting on us, was also on her cell phone, while serving us. The car had lots of small dings and scratches where it had hit things and the paint had chipped off. On the form the attendant gave us in the parking garage, none of these were checked off and should have been. When I told the attendant that there were many dings and scratches, she just told me to mark them off on the diagram but she should have really come out of the booth since she was not serving any customers at that point, and should have gone over the condition of the car with us.
