I'm gonna try and sound fair here - Love her or loathe her - It isn't her fault. QVC hired her, after I presume a number of screen tests, and she would've been compared with other candidates. I would also presume that whomever it was who hired her saw showreels of her previous work and would've seen that she's no shrinking violet. It's a little bit different to how it is when you start a job in a regular high street store, you're allowed to be unsure, a little bit nervous and it may take a little while for you to "find your feet". On a tv shopping channel you need fit in quickly and seamlessly. A big personality is one thing, but being full of oneself is another. Q need to be make sure that their shows are presented in a professional manner.
Talking about wanting to lick a product (even if she didn't actually do it) doesn't sound professional, neither does "Have you been warned about me?" It's not about "Me" and Q should recognise this and not let her, or any of the other presenters for that matter "run away with themselves". When viewers start complaining, I think it's gone a bit far. It's up to Q to make sure that their presenters aren't inviting loads of shitty feedback, they're supposed to be running the place. The feedback might sound cruel, but it's not unfounded. I'd soon be shown the door at work (or at least "spoken to") if I started talking to my customers like I was down the pub with my mates. The viewers, and the BAs need to be treated and spoken to in a respectful manner and it's up to management to ensure that this level of professionalism is upheld at all times, and they're not!
