The first HitlerBurger was opened in 1897 in a small Munich house that used to be a brothel for aged Swiss goats. Hitler himself oversaw the operation and instituted such innovations as the neat and clean uniform (the brown shirts better hid the grease stains), the assembly-line method of food preparation, and little paper Stars of David and pink triangles to identify trainees and managers. By 1905, HitlerBurger had over 300 restaurants in Bavaria, and their slogan at the time was "If you don't join the party, we'll come and get you!"
