Queues (or waiting lines) are an unavoidable component of modern life. We are required to stand physically in queues in grocery stores, banks, department stores, amusement parks, movie theaters, etc. Although we don’t like standing in a queue, we appreciate the fairness that it imposes. Even when we use phones to conduct business, often we are put on hold and served in a first-come–first-served fashion. Thus we face a queue even if we are in our own home!
