why do chefs say all day

Chefs say "all day" in the kitchen to communicate the total number of a specific dish that needs to be prepared at that exact moment. Instead of calling out each order individually, they combine all active orders to ensure accuracy, efficiency, and smooth service. This phrase helps the kitchen team track how many dishes they need to make collectively, avoid confusion or duplicate calls, and assess ingredient availability. It is commonly used in fast-paced restaurant environments to streamline communication and keep the workflow organized during service.
