OK, I have another question along these same lines...
What if we get a hit (on, for example, a non-customer purchaser) after regular business hours (example: 5:45pm through our drive-thru, or on a Saturday morning)??
What the heck does the poor teller do then? Confiscate the cash being used to purchase the monetary instrument, tell the customer to come back during regular business hours (with some cockamamie excuse), or what?? Is the OFAC hotline a 24 hour line?
