Final answer:
Fire sprinkler systems are not used to prevent theft by staff members but are for fire safety; instead, methods like surveillance and monitoring transactions are used. A cashier accused of theft can use these security measures to prove their innocence.
Step-by-step explanation:
Preventing theft by staff members in a retail setting involves various methods, particularly establishing a minimum level of security. However, certain techniques such as installing fire sprinkler systems are not designed for theft prevention. Implementing fire sprinkler systems is primarily for safety and reducing the risk and damage of fires. In our scenario, if a cashier at a retail store is facing accusations of theft, they must address this situation by providing evidence of their innocence, requesting a review of surveillance footage, or seeking support from coworkers who can vouch for their behavior. Establishing a minimum level of security can include measures like video surveillance, which could help the cashier in this situation. Higher security levels might also include monitoring systems that track transactions and prevent unauthorized access to the cash drawer. Insurance companies recognize these security practices and may offer incentives, like lower rates, for businesses that adopt them.
