His Brain Has Run Out Of Gas

(We have a policy where you must present a receipt if you filled up your gas tank before returning your car. Some cars take a while to move off of full.)

Customer: “Hi, I’m returning my rental car! It’s full of gas!”

Me: “Great! Do you have the receipt that shows you bought the gas?”

Customer: “Uh, no. You can see it’s full.”

Me: “Well, you drove 50 miles, so there will be a fee if you don’t have your receipt.”

Customer: “But it shows that it’s full of gas!”

Me: “Driving 50 miles used roughly two gallons of gas that you didn’t replace. I’ll need to charge you if you didn’t refill the tank.”

Customer: “Oh, no. You see, it didn’t USE any gas! It’s still on full!”
