Sample Capacity Calculation and Process Flow Diagram Problem:

Two people take the orders of customers, spending approximately $2$ minutes with each customer

$($order and payment collection$).$ The order is given to $1$ of $2$ sandwich preparers. On average it

takes $3$ minutes to prepare a sandwich. Two people are in charge of packaging the sandwich and

distributing the orders to the customers, which takes approximately $15$ seconds per order. The

customer exits and proceeds to fill their cup with soda, which takes approximately $1$ minute.

About $4$ customers can fill their soda on the soda station closest to the deli at one time.
