Q

Upon leaving the café, one boy paid his bill, while his friend handed the cashier a slip of paper with the number 1004180 on it. The cashier smiled and let him pass without paying. Why？
离开咖啡屋的时候，一个男孩付了账，他的朋友却递给收银员一张纸条，上面写着一串数字1004180，收银员笑了笑，让他不付钱走了。奥妙何在？

A

1004180 means“I owe nothing for I ate nothing.”
1004180意思是：“我不欠什么，因为我什么也没吃。”

点睛一笔

1004180读作“I O nothing four I eight nothing”，其中，数字1形似I，O与owe音似，数字0代表nothing，four与for音似，eight与ate音似，所以，这句话的意思是“I owe nothing for I ate nothing”。
