I dunno. It seems a bit presumptious to me. I know my own style better than some cue-card training script can ascertain.
I mean, would you ask the average Apple store employee what sort of haircut suits you? This is similar - but at least a bad haircut will grow out.
I've never had a bad experience with an Apple employee. If they said something to me about "hey, I think you'd love this band" and they are basing it on something they observed, like my embossed leather iPhone case, or my bright pink Michael Kors handbag, there's no harm in that.
I just don't see the point of getting outraged over something like this. There's so many things in life that are worth getting tuned up about. I don't think this is one of them. But, to each his own.
