1. Sam was alone in his shop when I dropped in. “That’s a real bargain at £43.89,” I commented, noting a fine electric cutter standing on the counter. “Not much profit for you at that price.” “Enough, and I’ll make a sale.” The old chap chuckled. “But here’s something for you. My mark-up on that cutter is exactly the same percentage as what it cost me in pounds.” Neat! What had it cost him?
