Which step is NOT part of the five basic steps of OSA?

The five basic steps of OSA, which stands for "Order, Sell, and Assist," are designed to create a positive customer experience and ensure effective service. One of the key components of OSA is the importance of engaging with customers throughout their visit.

In this context, greeting the customers, upselling appetizers, and expressing gratitude through a thank you are all integral parts of the OSA process. Greeting creates a welcoming atmosphere, upselling enhances the customer’s meal experience by encouraging them to try additional items, and thanking customers helps to foster customer loyalty and appreciation.

Requesting feedback, while valuable for improving service and customer satisfaction, is not typically included as a step within the established five basic steps of OSA. This task is often an additional practice that may occur after the completion of the transaction, rather than during the primary interaction steps. Thus, recognizing that requesting feedback is not a formal step in the OSA process clarifies why this is the correct answer.
