Entry in progress—B.P.
March 1960, Fast Food, “Fountain Service” by Harry Press, pg. 40, col. 1:
I entered pharmacy about 39 years ago. The first store I worked in had a soda fountain, and I fell in love with that end of the business.
In those days, soda fountain workers had a language all their own. In order to save (Col. 2—ed.) time, or just to be different, they used abbreviations or code words, or numbers for almost everything they ordered.
Some of these were quite clever, but some were often embarrassing to the customers. For this reason, most chain (Col. 3--ed.) stores and a great many independents have stopped using them.
Here are a few of the “codes” still used behind some fountains.
Hoboken—pineapple soda, chocolate ice cream.
