Problem
Construct a BPMN flowchart for the narrative description provided below.
A Burgerville customer pulls up to the drive through and orders a large beverage. The cashier on duty takes the customer's order and instructs them to pull up to the first window. At the window, the cashier processes the customer payment via cash, credit card, or gift card before providing a receipt. The cashier then instructs the customer to pull forward to the second window. The order prep on duty then assembles the order before asking if they would like a straw. If yes, a straw is provided with beverage. If not, just a beverage is provided. The order prep then thanks the customer as they exit.
