In food as in art, the setting up is the most important part to not scratch your set. Missing an ingredient in the middle of a rush or forgetting your white cane to highlight it can break your evening. Try to be ready for all eventualities, a little extra, which we don't keep à la carte, for a demanding client or a good pair of running shoes in case the police arrive in full Graff on your perfect wall. Hence the importance of having a good set-up.
