If a mistake is made in an order, the guest visits the vendor who processed the order and requests a reversal. If the employee agrees with the request, they can then put a pending reversal request on the guest’s wristband. At this point, if the employee is also trusted to approve reversal requests, they can immediately approve it.

Alternatively, if the organizer wants a manager or similar trusted individual to be required to approve reversals, the guest then visits the manager to get the request approved and balance added back to their wristband. As with all other WristCoin operations, this whole process can proceed seamlessly without internet connectivity being available.
