Your local grocery store is a psychological minefield (布雷区)，where even the bananas are ripe with mystery.
1．Southpaws (左撇子) have an invisible (看不见的) advantage
You've probably seen that stores keep go-to items—produce，meats，dairy—on the outer edge.But did you notice that most of them are set up to make you run counterclockwise (逆时针)? Ninety percent of us are right-handed，so we buy more when it's counterclockwise.You'll also often find the dairy section in the back left corner：Because dairy is likely on your list，stores make sure you take the longest route to get there.In fairness，it's also a more convenient place to put a fridge.
2．Everything is in its place
It's safe to say that nothing you see on a shelf is there by chance.The cookies on sale at the end of a passage are likely the result of smart product placement.More expensive items are usually placed at an adult's eye level，while colorful treats and other products for kids are positioned lower—to catch the attention of children.
3．Time goes by so slowly
Stores rarely have windows or clocks.With no reference to the outside world，customers can easily lose track of how long they've been there so that they can buy more.Grocery stores may use another trick to control your sense of time: small floor tiles (瓷砖)．
