I too have been very disappointed in the whole series.
In the tea dance thing, why weren't they allowed staff? Were we supposed to be amazed and shocked that one person found it impossible to serve 50 people? The equivalent in series 2 was the Oxford university dinner, where they had a team of waiters, and it was interesting to see how they managed people (like Harriet's father moaning at people!). This time they were left on their own. Why?
I just couldn't take such a ridiculous set-up seriously. One customer said 'would you wait 90 minutes in a restaurant'? Well, if the restaurant had one waiter, I wouldn't even go in.
The same goes for the cake thing, it was blatantly obvious they didn't have enough time to prepare and I felt desperately sorry for the fella who honestly tried his best, whilst the winker got someone else to do it and passed it off as his own.
I think Raymond likes the Winkers because they already run a successful business. Anything else he's not bothered about, they run a bar in central London, and that beats a) not even trying to cook b) constant brown-nosing and c) abandoning their concept completely.
What I also miss is the feedback session from other series. Does anyone else find the conversation between Raymond, Sarah and the other bloke all a bit forced? It's as if they're reading lines sometimes, I find it cringeworthy. It was better when you actually saw the contestants get a bollocking.
