I actually think Dave is more tolerable than droopy eyed div Sophie. I feel for him because of his weight and I think like many, it is likely a product of mental health issues. A lot of people choose to engage in unhelpful behaviour to cope and food is one of the few that are very visible to others. I agree he probably needs counselling and if he is gay, as an example, and feels he can't really ever act on that then it could explain his weight.
Now Sophie... She's just a knob.
