Paging Miss Manners! The recession is now eroding the very cornerstone of our society's system of etiquette: the willingness to pay for a business lunch. Literary agent Larry Kirshbaum says that people have turned into such tightwads, he's often reduced to conducting business over lunch at a cheap diner instead of Michael's and that one "top publisher" wanted to take him to McDonald's. "People are really afraid to spend money," he reflects. "Anything that smacks of too much fun or self-indulgence is being frowned upon." Well, it's understandable. A few slimmer expense reports, and the demolishment of Western capitalism will reverse itself in no time.
