_____, we decided to go up and speak to him. He was ________ pieces of leftover bread that he had collected from his housemates to make ________ for the birds that come there every morning.

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. 1., either in a supermarket, a bank or anywhere else.
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. 2.. For example, four bottles of the same milk will go faster than four different items.
3.
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. 4..
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.
Go left
According to US science writer Robert Samuel, around 90 percent of people are right-handed. 5. So heading to the left will give you a better chance of finding a faster line.
A. Be patient
B. Pick someone with a full cart
C. The items in their carts are also important
D. Each item in the cart only takes 3 seconds
E. It also gave tips on how to pick the fastest line
F. That means they will naturally choose lines on the right
G. How many people are ahead of you is one thing, and who they are is another
