In a Greek restaurant I sometimes eat at there's a TV set to some absurdly high color saturation, colors are at 180%. It's been like that for years. Nobody ever even commented on it, even though it is so very very clearly uncomfortably extreme.
At least when people think that ketchup belongs on steak, that's a choice they're making that only affects themselves. They don't insist on squirting it on your side of the table because you happen to be sharing a meal.
