商店的记账员把食物擦过扫描器。食品的价格就在屏幕上弹出了。计算器怎么会计算得如此精准？

The clerk swipes the food over the scanner. The price pops up on the screen. How did the computer get so smart?

打开计算器请等一会，我要从出纳员那里拿钱。二分钟后这是你的钱。

(opening the calculator) Please wait a minute. I'll get the money from the cashier, (two minutes later) Here's your cash.
