Prepare a process flowchart for the following scenario:

On your way to work, you regularly use the drive-through at Mac-Donalds to buy your usual breakfast of black coffee and a bacon, egg, and cheese bagel, but without the bacon. The process begins when you pull into one of the two lanes, where there is a speaker and a microphone. There are sensors in the ground under your vehicle, and they make a beeping sound in the headsets of the employees taking drive-through orders. Each lanes sensors make a different sound to identify which lane you are in.

You give your order to the employee, who inputs it into the system. The order and price appear on the screen next to the speaker/microphone. Once your order has been taken, the employee tells you the price and asks you to drive to the first window to pay. After you pay with either cash or a card, the order goes through to the second window and the kitchen, and the employee will ask you to drive to the next window, where you can pick up your order. The employee in the kitchen prepares your order and places your wrapped bagel in a bag while the employee at the second window gets your coffee ready and hands it to you, quickly followed by your bag of food.

The drive-through process is on a timer. Anything over a particular number of minutes (say four) is reported as to time-consuming, and the employee will ask you to park in the waiting bay. An employee will come out, confirm your order, and deliver your order to you out there. Then you drive off to work.
