They were honest questions: I'm not one to *****-foot around because it's 'not nice' to ask awkward questions. It's not being a jerk it's being inquisitive; if she doesn't know the answer then she should have just said so.
The point is that you were obviously asking wide-scoping Apple Engineering and Marketing based questions which obviously couldn't be answered by a simple Apple Store Rep.
You obviously knew it was out of her area of expertise, you obviously knew she couldn't either comment on or affect the problems you had. You were obviously doing it to just to be a d*ck.
Just my humble opinion.
