By retaining human involvement in the order processing loop, several advantages can be realized:

1. Order Editing: Waitstaff can make necessary edits to orders, such as when an item is sold out or if there appears to be a mistake.
2. Order Cancellation: Orders can be cancelled promptly, preventing unnecessary consumption of time and resources in the kitchen.
3. Age Verification: If legally required, age restrictions can be checked to ensure compliance.
4. Order Verification: Staff can verify the authenticity of orders and, when applicable, ensure that payment has been completed.

Furthermore, maintaining orders in a pending state before they are transmitted to the kitchen enables effective management of kitchen workloads, ensuring smooth operations.
