Scene: A bookstore
Customer: Can you help me find a book?
Me: Of course. Do you know the author or title?
Customer: Well, I was at the beach and I saw this girl reading a purple book. She looked like she was really enjoying it. I want that book.
Me: Ma’am, you’re going to have to be more specific. There are a lot of books with purple covers.
Customer: Can’t you search on your computer for purple books?
Me: Unfortunately, no.
Customer: In that case, I’ll take my business to a bookstore that has better computers.
