At this point, the cabin crew clearly was not happy with the would-be free drink gifter, and a flight attendant had some words with him. An American representative also boarded the aircraft to speak with the man in the jetway, and ultimately, he came back to retrieve his carry-on and left.
Genter says she overheard the flight attendant tell another passenger that the man would be rebooked on a later flight, but it seems he never was.
"The customer caused a disruption during the boarding process," American Airlines told Travel + Leisure in a statement. "We did offer to rebook the customer on a later flight, but he declined and we provided a full refund."
If anything, let this whole saga serve as a lesson that no matter how generous you're feeling, trying to pull a fast one on some eagle-eyed flight attendants won't get you very far. In fact, it might literally keep you from going anywhere.
