Step-by-step explanation:
One indicator that management can use to determine if a server is selling the menu is by analyzing the sales data. They can look at the number of orders placed for each item on the menu and compare it to previous periods or benchmarks. If a particular item is consistently selling well, it suggests that the server is effectively promoting and selling that item to customers.
For example, if a restaurant offers a new dish and the sales of that dish significantly increase after a server starts recommending it to customers, it indicates that the server is actively selling the menu. Likewise, a decrease in sales of certain items may suggest that the server is not effectively selling those items.
In addition to sales data, management can observe the behavior and interaction of the server with customers. If the server is knowledgeable about the menu, able to answer customer questions, and makes recommendations based on customer preferences, it indicates that they are actively selling the menu.
