Once a gentleman walked into an imposing used and rare book establishment. As one of the clerks went to assist him, the gentleman asked the price of a certain title he wished to purchase. The young clerk looked at the price posted on the book and said,
"That book is one dollar, sir."
The fellow began to haggle with the clerk over the price. The clerk assured him that the correct price for the book was one dollar and no lower. Contrary to popular belief, haggling is not routinely encouraged in such establishments, and the man soon realized that his efforts were going nowhere. Whereupon, he insisted on speaking with the proprietor.
Upon receiving this summons the proprietor stopped his work and walked out to the storefront. The customer began,
"What is the price of this book?"
"One dollar and a quarter."
The gentleman was confused and replied,
"Your clerk just said it was a dollar."
The proprietor studied the book for a moment, then addressed his customer,
"Yes, it was a dollar. But now you're wasting my time ..."
