I haven't flown on BA metal for a few years now, and I remember getting something like 20,000 as compensation for a malfunctioning IFE in CW some years back. No IFE is a tiny nuisance in my book, but having to choose between a regular meal (when vegetarian was ordered for ethical and health reasons) and being forced to fast for many hours (I happened to get to the flight after a long day with hardly any food, and skipped the lounge), is extremely aggravating. Not sure if non-vegetarians can fully understand this, but I understand your point about waste of time in trying to get more.
