美国咖啡馆使用礼貌用语可享折扣
A cafe in Virginia has come up with an ingenious new strategy to convince customers to be more polite.
美国维吉尼亚州的一家咖啡馆提出了一个别出心裁的策略，来说服顾客变得更加礼貌。
The business offers financial rewards to those who mind their p's and q's.
A sign outside the establishment advertises different costs for a cup of coffee depending on how courteous the customer is when ordering.
The prices are listed with the typical phrases a patron might use when placing their order.
They include: 'Small coffee' at $5 (£3.85), 'small coffee please' at $3 (£2.30) and 'hello, one small coffee please' at $1.75 (£1.35).
