And that amount of time is an average of 41 seconds per person. 3. . This means if there are five people ahead of you, each with 10 items in their carts, the waiting time will be 355 seconds. But if there is only one person ahead of you, with 50 items in the cart, the waiting time is 191 seconds. You do the math.
