Let me give you an example. If I were to order three scrambled eggs, dry wheat toast, and hash browns, the waitress would face the grill and yell out loud – "Mark: Triple scrambled dry wheat plate."
The cook would then quickly take a large dinner plate, turn it sideways, and place a tub of jelly upside down at the six o’clock position.
