Queue areas are places in which people queue (first-come, first-served) for goods or services. Such a group of people is known as a queue (British usage) or line (American usage), and the people are said to be waiting or standing in a queue or in line, respectively. (In the New York City area, the phrase on line is often used in place of in line.) Occasionally, both the British and American terms are combined to form the term "queue line". Examples include checking out groceries or other goods that have been collected in a self service shop, in a shop without self-service, at an ATM, at a ticket desk, a city bus, or in a taxi stand. Queueing is a phenomenon in a number of fields, and has been extensively analysed in the study of queueing theory. In economics, queueing is seen as one way to ration scarce goods and services. Types Physical History The first written description of people standing in line is found in an 1837 book, The French Revolution: A History by Thomas Carlyle. Carlyle described what he thought was a strange sight: people standing in an orderly line to buy bread from bakers around Paris. Typical applications Queues can be found in railway stations to book tickets, at bus stops for boarding and at temples. Queues are generally found at transportation terminals where security screenings are conducted. Large stores and supermarkets may have dozens of separate queues, but this can cause frustration, as different lines tend to be handled at different speeds; some people are served quickly, while others may wait for longer periods of time. Sometimes two people who are together split up and each waits in a different line; once it is determined which line is faster, the one in the slower line joins the other. Another arrangement is for everyone to wait in a single line; a person leaves the line each time a service point opens up. This is a common setup in banks and post offices. Organized queue areas are commonly found at amusement parks. The rides have a fixed number of guests that can be served at any given time, so there has to be some control over additional guests who are waiting. This led to the development of formalized queue areas—areas in which the lines of people waiting to board the rides are organized by railings, and may be
