2 . We’ve all been there - when lining up at the supermarket checkout counter, the lines next to us always seem to be moving faster than the one we are standing in. Recently a report by The New York Times looked into the math and psychology of queuing.
Study the customers
It’s important to know who the customers are. For example, if they are elderly people, they are more likely to move slower.
US mathematician Dan Meyer believes that a cart full of items doesn’t tell the whole story. “Every person needs a fixed amount of time to say hello, pay, say goodbye and leave,” he said. And that amount of time is about 4l seconds per person.
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.
