Entitlement sits on the staff record and the balance is on screen at the counter, so the person handing over garments can see what is still owed without adding anything up. An approval records the approver, the sets approved and the FTE it was based on. Take less than the entitlement and a credit slip prints for the balance.
Going over is allowed — it just asks for the approval first, which is the only difference between a helpful exception and an unexplained one.
