4. Be polite to salespeople, but don't feel like they're your new best friends. 对销售人员要礼貌,但别把他们当成你新结识的最要好的朋友。
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.
不要因为担心伤害到他们的感情而去购买,也别因为他们的努力帮助或解说就非得买某样东西。同时,还是要对店员的努力表示尊重。
