Trivia: What were attendants who worked at soda fountains called?
Correct Answer: Soda jerks
So why is this answer correct? : This nickname, due to the jerking motion used to pump soda water, was popular from the 1920s through the 1950s. Before soda dispensers came along, the soda jerk’s job was more tedious. The attendant mixed carbonated water and phosphate with flavored syrups at the counter, creating a variety of different sodas from scratch.
