Certainly, if I am going into a restaurant to eat an expensive meal, I expect to be served something that I couldn't have done myself.
I wish! Usually these days I think I can do better. But then I'm not eating at high end restaurants! One ambition I have is to go to Heston Blumenthal's Fat Duck. I once booked a place there for my birthday (you need to book months ahead) and managed to fall over and break my pelvis the week before... sad. I have a long list of other Michelin starred restaurants where I'd like to eat.
