I would suggest to those commercial customers who send their money bags, to drop them off in the night drop. I beleive if they are informed that the bank is required to identify the runners who come in with the money bags if the cash in the bags total more than $10K, they will deposit cash under the reportable limit and the bank may inadvertantly help the customer structure the deposit.
It is a sticky situation. Since the runner who comes in is not part of an armored car service, the best suggestion is to inform business, who do not want their deposits verified when the money bag is dropped off, to utilize the night drop.
These are only my opinions...I know there are other suggestions out there, but thought I would put in my 2¢ worth...

Hope this helps...
