The Cash Register Confusion If you work as a cashier in Los Angeles, you expect customers to pay the exact amount or simply hand you a large bill and wait for their change. But if you watch a Japanese customer pay at a convenience store, you might witness a mathematical transaction that completely breaks a Westerner’s brain. Imagine the total bill is 680 yen.

The Impossible Turnaround Time When an airplane or a long-distance Amtrak train arrives at its final destination in the United States, cleaning the cabin is a slow, time-consuming process that can take anywhere from 20 to 45 minutes.
