Dave: I agree w/jbedsole that you would have to make the funds available for w/drawal, but I disagree that the customer can force the bank to issue a cashier's check for the w/drawal.
The UCC (ยง3-409) permits a bank to refuse to certify a check. I think that a cashier's check is the equivalent of a certified check, b/c, upon certification, the check becomes an obligation of the bank that certified the check (in the same way that a cashier's check is a check drawn on the bank and not an account of the bank's customer).
From a practical standpoint, once the funds become available, the customer can w/draw cash OTC. If you would allow the customer to w/draw cash, the only reason I can think why you wouldnt give this same customer a cashier's check is if you thought to do so would result in a separate problem for the bank (like getting pulled into a lawsuit over a forged endorsement, etc.).
