An efficiency expert concluded his lecture with a note of cautionâŠ. âYou don't want to try these techniques at home.â âWhy not?" asked somebody from the audience. âI watched my wife's routine at breakfast for years," the expert explained. "She would make lots of trips between the refrigerator, stove, table and cabinets, often carrying a single item at a time. One day I told her 'Hon, why don't you try carrying several things at once?'" âDid it save time?" the person in the audience asked. âActually, yes" replied the expert. "It used to take her 20 minutes to make breakfast. Now I do it in seven".
