> "negotiate"

A negotiation with an entity that "can" (for varying definitions), and will, have you trespassed or otherwise forcibly removed is not a particularly fair "meeting of the minds". It's somewhat what happened here. Passengers _were_ negotiating. Someone offered to leave for $1500, then $1300, on video, and the gate agent responded. "Not happening. Someone's getting off or the plane's going nowhere", and look at the result.

That's "my way, or the highway", not a negotiation in any meaningful sense.
