I dont mind her, actually I quite like her, Although I would have thought this position would not suit her. They need an observer, someone who can report to Alan what they saw. As Alan says, they are his eyes and ears.
Considering how little screen time they get, I dont think its a vital role. True they have been bigged up on YBF program, in reality, they have very little screen time, and contribute very little to the program. I think this series, is the most I have heard from them.
Normally they speak in the task, Nick broker with this convention when it came to the perfume task. They utter the odd sentance in the boardroom. They may utter an odd sentance when the three are sent out, and Alan discusses who to fire. All in all they say about 2 - 4 sentances an episode.
I am not demeaning them, they do an excellent job, however to the viewer, the role is somewhat non-essential. You would hope the editor will show all things relevant to the task.
Not sure about the thread title, of calling her stupid....as she certainly isnt. OP have you created a £multi million business from scratch? If not why not, as even a 'stupid' person can do it.
