Pulling into my service station 45 minutes late one morning, I shouted to the customers, "I'll turn the pumps on right away!" What I didn't know was that the night crew had left them on all night. By the time I got to the office, most of the cars had filled up and driven off. Only one customer stayed to pay. My heart sank. Then the customer pulled a wad of cash from his pocket and handed it to me. "We kept passing the money to the last guy," he said. "We figured you'd get here sooner or later."
