Final answer:
At Dollar General, when the EAS system is activated, typically the cashier is responsible for engaging with the customer to find out why the alarm was triggered.
Step-by-step explanation:
When the Electronic Article Surveillance (EAS) system is activated at Dollar General, it is typical for the cashier to address the situation. The cashier would talk with the customer to determine the cause of the alarm. This is part of the customer service responsibilities at most retail stores, and though the store manager, security personnel, or customer service representative might assist, the cashier is usually the first point of contact since they are at the checkout and can quickly check the purchased items for any security tags that may have not been deactivated or removed.
