The moment an order goes to the kitchen, its items are locked. Staff can add new items, but cannot change or delete what was already sent. Choose how strict: owner-only, manager-PIN approval with a reason, or permission-based.
Every cancellation — with who asked, who approved and why — goes to the audit log and raises a fraud alert to the owner. KOT reprints are counted and printed as “REPRINT”, so the same ticket cannot be used twice.
