Trivia: People who served drinks at soda fountains were called what?
Correct Answer: Soda jerks
So why is this answer correct? : In the 1930s and ’40s, soda fountains were manned by soda jerks, named for how they pulled the soda spigots. In addition to pouring beverages, soda jerks were known for entertaining customers with their unique slang. For instance, water was called “Hudson River ale,” and milk was known as “bovine extract.” As fast-food chains replaced local soda fountains, soda jerks became a thing of the past, as did their unique lingo.
