<h2>A Tough Customer</h2>Mrs. Rosenbaum was known for being a difficult customer at the local grocery store."Give me two pounds of oranges," she asked the saleswoman, "but I need you to wrap every orange up in separate pieces of paper.""And three pounds of cherries, and wrap up every one in a separate piece of paper, too."The saleswoman obliged."And what is that over there?" Mrs. Rosenbaum asked, pointing to a bushel in the corner."Those are raisins," said the saleswoman, "but they are not for sale."
