4. Be polite to salespeople, but don't feel like they're your new best friends. 對銷售人員要禮貌,但別把他們當成你新結識的最要好的朋友。
Don't buy something because you're worried about hurting their feelings or having made them do a lot of work helping you or explaining products to you. At the same time, be respectful of clerks' efforts.
不要因為擔心傷害到他們的感情而去購買,也別因為他們的努力幫助或解說就非得買某樣東西。同時,還是要對店員的努力表示尊重。
