Beagle,
The incessant chinese water torture of inflight hard-sell would drive you and others to the edge. It could induce air-rage. Your defence would then be that the airline had high-jacked your ears & brain, (even spam adverts on the IFE), driven you to explode and therefore been a major contributory factor in causing A.R. No case to answer.
M' case rests, M'lud!
