Monitoring the self-checkout lanes:
Self-checkout managers need to keep an eye on all of the self-checkout lanes to make sure that they are operating properly and that customers are not having any problems.
Assisting customers: Customers may need help with tasks such as scanning items, using coupons, or paying for their purchases. Self-checkout managers need to be able to provide assistance in a timely and courteous manner.
Preventing theft: Self-checkout lanes can be a target for theft, so self-checkout managers need to be vigilant in watching for suspicious activity. They may also need to intervene if they see a customer trying to steal.
