Final answer:

Step-by-step explanation:
To establish a basic control system in a restaurant, three tactics that could be implemented immediately include inventory audits, employee access controls, and utilizing a point-of-sale (POS) system for transaction tracking. Regular inventory audits ensure that stock levels are maintained correctly and help in identifying discrepancies or losses. Implementing access controls for employees can prevent unauthorized access to certain areas and ensure that only qualified personnel handle specific tasks which can reduce chances of theft or error. Finally, a POS system is beneficial for tracking transactions accurately and provides real-time data which helps in managing the restaurant's finances and customer data efficiently.
