Yeah, I've never really understood being _offended_ by being asked to do something relatively simple (and honestly, those are actually pretty good problems). I might consider it a little amusing if somebody asked me to write FizzBuzz or something really basic, but I would shrug my shoulders and do it.

I agree, although I might be offended if an interviewer spent more than a few minutes on such things once it was clear that you could do them. However, that's more about not respecting the value of your time than the difficulty of the problem(s), just like expecting you to do a day of homework problem(s) before they even meet you.
