Answer:
The implosion of ZeekRewards has made this a common question. Bank customers have found out they have been duped and want their bank to fix it. Whatever lengthy analysis of the overall situation might be offered it will still come back to a simple, "We can't fix it."
First, your customer did not authorize the payment (your bank did) so your customer has no right to stop the payment. Second, your bank accepted the check at the time your employee signed it and you cannot change your mind later.
Any processes your bank may have for handling lost or stolen cashiers checks under state law do not apply here.
