I think it's exactly what she's there to do, and she's only perpetuating the old adage that goes "this is exactly why models shouldn't talk". If you're picked out to get camera time backstage you should revel in it, say kind things about the designer etc, because how many other jobs are there where you get paid thousands an hour to walk ten yards? I mean think about it, sometimes you think why isn't the interviewer going to my favourite model? Whereas I think it's nice that girls like Natasha Poly and Caroline Trentini always are polite and inviting. I'm not asking them to do charity or anything but manners don't cost anything, and again I'm not talking about Angela specifically, I'm talking about all the models featured in that segment. Why shouldn't you be immune to it? Are they above and beyond mortals who encompass them, I get angry but I don't lash out. Imagine how the interviewer felt? He/She was just doing their job as well.
Okay I'm going to stop now. I'm really puzzled as to why people are condoning this kind of behaviour.
