Frontier Airlines worker refuses to let a man check into his flight, taunts him as he tries rushing so he doesn't miss his flight.

Man: "I paid for a ticket."

Worker: "You didn't pay $25 for an agent assist fee. Hello? And you thought you was gonna get on your flight. And you thought you was gonna get on your flight. And you thought you was gonna get on your flight. And you thought you was gonna get on your flight. And you thought you was gonna get on your flight. And you thought you was gonna get on your flight. And you thought you was gonna get on your flight."

Infuriating.
