Along those same lines my little brother was late for a flight so he left his rental in front of the airport (back in the day) and went up to the counter and said, “Here’s the key. Send me the bill. The car’s out front.”
Then she said, “You can’t leave it there.”
He said, “I’m late for my flight so I’m leaving it there. You can add something to my bill if you have to.”
She said, “You can’t leave it there.”
He said, “I bought insurance, right? I’m going to go drop a match in the gas tank. You can have the burned-out husk towed and apply for the insurance.”
She said, “Have a nice flight.”
Awesome brother!!! Clever, also!
Last time I flew, they changed my departure gate twice.
The gates were on opposite sides of the airport.
