What does the term "bag and tag" refer to in a restaurant context?

The term "bag and tag" in a restaurant context specifically refers to the process of placing a complete order into a heat-retaining bag along with a label that identifies the order. This process ensures that the food remains at the appropriate temperature until it is delivered to the customer and allows for easy identification of the order contents. Using a heat bag helps maintain the quality of the food during transit, which is crucial in providing a good customer experience. The labeling is also important for efficiency, as it helps both the delivery staff and the kitchen staff keep track of which orders are ready and where they are going, ultimately leading to a smoother operation.
