In-Flight Distraction on United Airlines

It's enterprising of United Airlines and Direct TV to offer passengers on long-distance United flights a selection of movies and sports events to watch on a small TV screen embedded at the top of the seat in front of them. But it's simply unfair to impose that "pick one" display on the eyeballs of a passenger who doesn't want to view it. True, it can supposedly be turned off from a button on the seat controller. But what if that button doesn't  work? "I'm terribly sorry," said a sympathetic United steward as we settled into a three-and-a-half hour flight. "There's nothing I can do about it. But I'll write it up." We trust he did. (On the return trip, a few days later and in a different airplane, the "off" button worked.)
