"Boss, the items I bought clearly cost fifteen yuan and sixty cents, and I gave you twenty," Fang Yi said as he held a plastic bag in front of a convenience store, dressed in a T-shirt, beach shorts, and flip-flops, looking every inch the part of an ordinary townsman. "You owe me four yuan and forty cents, so why did you only give me four yuan? There's still forty cents missing."
The convenience store owner, flustered, replied, "Isn't it just forty cents? Here, take fifty cents instead." Saying that, the owner took out a fifty-cent note.
Fang Yi took it, pocketed it, and walked away from the store. The owner muttered curses under his breath behind him, but Fang Yi didn't care. Wasn't forty cents still money?
