There's a clip of them on the Apprentice website arguing about whether the perfume should be "Dual" or "Duel" and Alex says at least twice, "OK we'll go with "Dual" and Helen keeps going "Alex, what's the problem, why do you think there's a problem?"
I don't like Alex but Helene was deliberately being difficult, unhelpful and obstructive. I could work with him but I don't think I could work with her.
