• The checkout status becomes Canceled and its Real Time status becomes Canceled, so it leaves the board and the summary counts.
• If a cancellation fee applies, it is recorded on the order as paid.
• If you chose a refund, the refund is recorded (and the card refund / wallet credit issued) exactly as on the Customer Orders page, and the customer receives the standard refund communication for that flow.
• If a courier had already been dispatched (order status Waiting), cancelling from the KDS marks the Sprwt order Canceled but, in the current version, does not call Uber to cancel that active courier trip — the automatic Uber cancellation only fires if the order's Real Time status had already reached Finished while an Uber delivery was still on file, which is not the normal case. If a courier is genuinely still en route when you cancel, also cancel the delivery directly with Uber (or from Integrations) so it isn't left running.

In the current version the KDS cancel does not send a dedicated "order cancelled" message to the customer beyond what the refund process itself triggers, and it does not raise the internal "Order Cancelled" admin notification (that notification is only created by a different cancellation path the KDS doesn't use).
