Supermarket customer service representatives, also known as courtesy clerks or customer service clerks, work at the customer service counter to provide a positive shopping experience for grocery store customers. Providing a positive customer experience involves answering questions, offering product knowledge, guiding guests to correct isles, checking prices, and providing carry out services. In addition, customer service representatives work to maximize sales by providing prompt, friendly customer service. Grocery store courtesy clerks minimize loss by providing continuous customer service and following company procedures. During busy periods, customer service clerks may need to check out customers on the cash register or bag groceries.
