Drive Definition and 516 Threads

A drive-through or drive-thru (a sensational spelling of the word through), is a type of take-out service provided by a business that allows customers to purchase products without leaving their cars. The format was pioneered in the United States in the 1930s by Jordan Martin, but has since spread to other countries. Hillcrest State Bank, Dallas, Texas, installed the first drive-through banking system in America. It was a George Dahl designed building, constructed in the 1920s, across from SMU. The second recorded use of a bank using a drive-up window teller was the Grand National Bank of St. Louis, Missouri in 1930. The drive-up teller allowed only deposits at that time.Orders are generally placed using a microphone and picked up in person at the window. A drive-through is different from a drive-in in several ways - the cars create a line and move in one direction in drive-throughs, and normally do not park, whereas drive-ins allow cars to park next to each other, the food is generally brought to the window by a server, called a carhop, and the customer can remain in the parked car to eat. However, during peak periods, to keep the queue down and avoid traffic flow problems, drive-throughs occasionally switch to an "order at the window, then park in a designated space" model where the customer will receive their food from an attendant when it is ready to be served. This results in a perceived relationship between the two service models.
Drive-throughs have generally replaced drive-ins in popular culture, and are now found in the vast majority of modern American fast-food chains. Sometimes, a store with a drive-through is referred to as a "drive-through", or the term is attached to the service, such as, "drive-through restaurant". or "drive-through bank".
Drive-throughs typically have signs over the drive-through lanes to show customers which lanes are open for business. The types of signage used is usually illuminated so the "open" message can be changed to a "closed" message when the lane is not available.
