Yesterday I was standing in the kitchen eating my lunch while listening to Dave Barry on Topical Currents and thinking this is no way to consume a meal. But then it occurred to me that the latest thing in the workplace is the stand-up desk, or, in some offices, the treadmill desk. Sitting, someone has said, is the new smoking. So I started to feel better about eating my beef and broccoli while on my two feet. So much better, in fact, that I thought of opening a restaurant with high-top tables and not a single chair. It would allow diners to communicate with wait staff eye-to-eye, and minimize, if not eliminate, under the table dealings. And, when the check arrived, people would be in prime position to fight for it.
