Which of the following positions is NOT part of the 4 drive-thru positions?

The position that is not part of the four drive-thru positions is the server. In the context of drive-thru operations, the primary roles typically include the window attendant, who interacts directly with customers at the drive-thru window, the expeditor, who prepares orders and ensures they are accurate, and often the switchboard operator, who takes orders from customers and coordinates the flow of traffic.

The server role, on the other hand, generally refers to positions in a dine-in environment where servers take orders at tables and deliver food to customers inside the restaurant. This function is distinct from the specialized positions focused on drive-thru service. Each of the other roles listed is specifically designed to optimize the efficiency and customer experience in a drive-thru setting, while the server does not fit that specific operational model.
