Now that I am living by myself, I often opt for eating breakfast at work. And, our local cafeteria has a short order cook who will fix any thing that you want for breakfast.
Once the cook has your order, you take your order slip to the cashier and pay for your food. And, by the time you get back to the grill, your food is ready.
Now, while the cook is fast, the cashier is, well, a little slow. So, by the time you finally pay your bill, your food is ready.
