In 1921, entrepreneurs Jessie G. Kirby and Reuben Jackson opened the first restaurant that was specifically designed to serve people in their cars.
At the original Pig Stand in Dallas, Texas, carhops would take motorists' orders as they pulled up in their automobiles, allowing drivers to grab a quick meal without leaving their cars, according to the Texas Observer.
Kirby and Jackson's restaurant was an instant hit, according to Oak Cliff Advocate magazine, and quickly expanded into dozens of locations in several states.
