Answer:
To implement and advertise a policy that any customer who does not receive a reciept is entitled to a free burger.
Step-by-step explanation:
Internal control is the process by which an organisation's objectives are met by ensuring efficiency of operational procedures, reliable financial reporting, and compliance with regulations and policies.
The normal procedure in Mamma's burgers is for Jodi to ring up customer orders on the cash register. Since she is taking the money and pocketing it occasionally, the best internal control policy is to advertise that any customer who did not receive a receipt will be entitled to a free burger.
This will give the customers incentive to report cases where reciepts are not given. The measure will act as a deterrent to Jodi.
