There was once a man who owned a book store, filled with all manner of books written in multiple languages. His customers would come to him because they knew he could help them find just the right book for them. And they understood that as the purveyor of fine books, he was the expert and they trusted his judgment. Or so they said.

Now, the book store owner was also an author, and he had written many books, some specifically for well-paying customers who wanted a book that no one else could own. A book just for them, because he was the expert and they trusted his judgment. Or so they said.

One day a new customer came into the book store and, after discussing their needs with the proprietor, found and selected just the right book for them. The only thing they requested was a different dust cover, one that was custom-created to match the decor of their personal library. So the proprietor labored long hours to create a new dust cover for the book, and the customer was happy with the results.

But soon after the customer returned. "We are not happy with Chapter 16. It does not fit well with our interpretation of the story. We want you to rewrite the chapter, and make it fit our purposes better."

So after much discussion, the book store owner agreed to rewrite the chapter. He was a clever man, and had a keen grasp of the language in which the book was written, but he was not familiar with the characters, plot, or storyline of the book, and while he knew the language, the author had written it in a somewhat peculiar dialect that was difficult to grasp at times.

After many hours of research and poring through the book to discover all the characters, their idiosyncrasies, their connection to one another, and the original chapter’s impact on the storyline and plot, the book store owner set out to rewrite the chapter to fit the customer’s needs. He quickly found that there were hidden subtexts, references to characters and themes from other novels by the same author, and connections to works by other authors with whom he was unfamiliar.

So he went to the customer and said, "While I certainly understand the language, and have written many books of my own, to rewrite this chapter will take quite a bit longer than originally thought, and cost you considerably more for my time and effort, as this extra work is out of scope." When the customer objected and wanted to know why, the proprietor did his best to explain to the customer that there were subtexts, and references, all of which were unfamiliar to him. But the customer said, "I still don’t understand. You are the expert! You talk about subtexts and references and hidden plot twists, but these are your terms. And besides, the last writer I employed was able to write an entire novel, much like the one I purchased from you, in a very short time!"

When the proprietor tried to explain that the other writer (whose work he had seen) had created his works extemporaneously, free of the constraints of existing plots, characters, themes, and the like, the customer was unmoved. "You say you are the expert, so I trust you to be an expert and write this chapter. But I shall not pay extra for it as it should have already existed in the form I wanted when I bought the book. And besides, there are other parts of the book that I want embellished that you have given me estimates on, and I don’t understand why those will be difficult, either. But, you are the expert…"

After several more rounds of this, the proprietor returned the book to the customer, thanked him for his business, and asked him never to darken his doorstep again.
