Back in the 1970s I was a short order cook while attending college and the waitress’ tickets given to cooks would reading something like: “Chik whip,” which meant fried chicken with mashed potatoes.
The different short order ‘codes’ are a neat piece of Americana. The standardized communication chain from menu listing -> customer order -> waitstaff order -> short order cook is pretty interesting.
Awesome that you got to experience that.
