6. Test Purchasing
- Consider using your own test purchasers to assess staff performance, and use results to improve training and procedures.
In the event of a FAILED Test Purchase Operation or an Under-Age Sale of Restricted Goods you may be able to avail yourself of the Due Diligence Defence, i.e.
If a sale occurs, you may avoid prosecution if you can prove:
- All reasonable steps were taken to prevent the sale
- Staff were trained and followed procedures
- Systems were in place and monitored.
Summary:
Preventing underage sales is a legal obligation and a key part of protecting children from harm. By implementing robust systems, training staff, and maintaining records, you can stay compliant and safeguard your business.
