Picking up the car went smoothly. The car was very new and any scratches were noted during the inspection. However, when returning the car, I called ahead to ask about the type of gasoline to use and mentioned that I might return it around 11 AM, but hadn't confirmed the time. In the evening, I was delayed finding a gas station near the airport, and the rental company kept calling to hurry me up. They eventually said if I wasn't back within half an hour, they wouldn't wait, which made me furious. They told me when picking up the car that a call 10 minutes ahead would be enough, but then they said they weren't open 24 hours. This made me very anxious. I drove over 100 mph back to the airport once I found the gas station, only to find out they were indeed working. I think the staff member just didn't want to wait and wanted to go to sleep, which really upset me!
