Although my GPS guided me to a Shell gas station down the road, I saw this "Airport Express" gas station sign closer to the airport, so I stopped here to fill up the gas tank of the rental car before returning it. The gas station had a big sign that says "LOTTO" I noticed while I was getting the gas.
When I finished filling up the tank, I pressed YES for receipt. It said "PRINTING RECEIPT" but then it said "CASHIER HAS YOUR RECEIPT". I hate it when this happens. Especially if I go inside and have to wait for my turn to get the receipt.
And "Voila!" There were 8 people lining up for one cashier trying to buy "LOTTO"!
I would NOT recommend this gas station to business travelers who tries to fill up the gas tank just before returning the rental car at Charlotte - Douglas International Airport, especially when you are in a hurry.
Airport Express is no Express. It's Local.
