Like all master craftsmen, Buffett prizes consistency. Marshall Weinberg of the brokerage firm Gruntal & Co. recalls going to dinner with him in Manhattan. “He had an exceptional ham-and-cheese sandwich. A few days later, we were going out again. He said, ‘Let’s go back to that restaurant.’ I said, ‘But we were just there.’ He said, ‘Precisely. Why take a risk with another place? We know exactly what we’re going to get.’ And that,” says Weinberg, “is what Warren looks for in stocks too. He only invests in companies where the odds are great that they will not disappoint.”
