at a time when lots of people are trying to cut down on sugar
And THAT is precisely why he's fighting back so fiercely 
I know that, in Apprentice Land (and most of big business), all they care about is the Benjamins and keeping customers just about satisfied enough that they don't bother complaining; but I actually think that it weakens the inherent value of a luxury brand to have hundreds of branches across the country - especially if, as Harpreet hopes, you end up offering it out as a franchise.
If you're Argos selling basic toasters for £5, by all means have a store on every high street, stack 'em high and see 'em flooding out the door; but how can you trade on a sense of exclusivity and 'specialness' when you're everywhere?
Bettys Tearooms have been going for over a century, but they still only have six outlets - granted they're all in one (historically, now divided) county, but people seek them out specially and happily pay a premium price when there for a real sense of occasion, which I'm really not certain would still be the case if they were as ubiquitous as Tesco cafes.
I'm also amazed that nobody pointed out the (non-pyjama-wearing) elephant in the room with the pyjamas advert: they were trying to sell matching nightwear for the whole family including the dog - but they only had a man and woman and stuffed toy dog wearing them in the ad - no children or actual dog. If you can't even make your weak gimmick work (or bother to actually portray it) in your advert, how are potential customers meant to be inspired to pay a lot of money to recreate it in real life?
