Heh. You say that "I'm sorry, now are you satisfied?" is the apology of someone who thinks they did nothing wrong, but I think it's a bit more complicated than that. It strikes me as a dominance issue - "there, I did what you wanted, and you're still not happy, so too bad!"

And in a sense, there's some "I did nothing wrong" but if you asked such a person to judge the same situation with the roles reversed, they'd agree it was wrong. They might think it's not wrong because *they* don't owe (decency/courtesy/whatever) to the person they've just "fine-I'm-sorry-satisfied".
