Dull ? With a huge warm smile and enthusism for her job ?
I think Vicki is lovely

I do like Vicky but that giggle can be annoyingly inappropriate.

An example from this week: Zoe had finished the Frock section and was solo to camera introducing the next section, in a straight manner and yet we still got to hear Vicky's giggle(-for-absolutely-no-reason-whatsoever) as she sat alongside Zoe, off camera.

So while it can be endearing at times, it is often frankly bizarre and occasionally rude.
