It was amazing to me then, and still is, that so many people who wander into bookshops don't really know what they're after--they only want to look around and hope to see a book that will strike their fancy. And then, being bright enough not to trust the publisher's blurb, they will ask the book clerk the three questions: (1) What is it about? (2) Have you read it? (3) Was it any good?
