At Allen & Overy what our customers want is the answer. They want an answer which is timely, accurate and authoritative. I could amplify this bald statement by saying that sometimes the customer wants to know what the question will be. Not long ago a partner said to me that what he really wanted was that I should be able to tell him what the questions would be that the client would ask him at a reception that evening. Perhaps another way of putting it is to say that he wanted the knowledge he did not have at that moment.
