A menu that routes a request
Customer: "I need to change my delivery address." Bot: "Has this order shipped? I can help route the request."
A fixed menu works when each choice leads to a known next step. It does not need AI. Read an authoritative shipping state before allowing an address change; the customer's answer alone is not permission to edit the order.
If the answer does not match a choice, retain the original message and offer support. Measure whether the request reached the right team, not how many menu replies were sent.
