A man posted a video to TikTok where he cooks a steak in a Delta lavatory. He puts a Sterno can in the toilet, lights it, and places an aluminum grilling sheet over the seat. Then he puts the raw steak on the sheet and pours white wine over it to marinate (perhaps it’s an old steak he’s trying to hide the spoiling flavor on, a good piece of meat should never require this!). He plates it and returns to his seat. There’s no question he should be banned from the airline, and probably charged with a crime if this really happened as-shown, for lighting a fire in the lavatory.
