Fact of the Day: drive-thru
The first drive-thru food establishment was that of the hamburger
chain Jack in the Box. The first Jack in the Box drive-thru was called a
"food machine" when it opened in 1951. The building contained only a
kitchen with enough room inside for one employee to transact orders and
another to prepare the food. Two-thirds of all Jack in the Box sales are
still transacted via the drive-thru, even though most restaurants now
feature indoor and outdoor dining areas.
