During a lunch rush at our Denver diner, we had 40 people waiting and three servers calling out orders at once. I started using simple location codes like 'front corner' and 'back booth' over the walkie, and suddenly the kitchen knew where everything was headed. Does your spot have a shorthand system that keeps the floor and kitchen on the same page?
Oh man, you could take it further and just number the tables on a little grid taped to the pass, so "front corner" becomes something like "A3" in two seconds flat. Once the kitchen stops looking up to figure out where the food goes, tickets move way faster.
