A Walmart People Greeter welcomes customers as they enter and exit the store, providing a friendly first point of contact and assisting with directions or store information. They may also check receipts, monitor for lost items, and support store security by observing activity at the entrance. In addition, greeters often help customers with carts or answer basic questions about store layout and promotions. The role involves standing for much of the shift, interacting with a diverse array of customers, and occasionally collaborating with store management or the loss prevention team.
