I feel that they are wasting a lot of time on pointless things that have nothing to do with cooking. The whole "first in line to get one wrong" thing was ill-conceived, and I agree that Kev's choice seems like gameplay that backfired.
Moving on a bit, what was the point of the challenge that Fillipo won, where he was allegedly going to be given "a massive advantage"? Turns out his massive advantage was, umm, he got to pick whether they used tomatoes, bacon or lettuce, before being sent straight back into the group to face the next challenge. In other words, no advantage or reward for winning at all, they might as well have skipped the previous challenge altogether.
Oh and the McDonalds kid is either brave or insane, is it any wonder the judges didn't want to taste CRAB CUSTARD dessert with peas or whatever it was? Blech.
