In most cases,this action will produce results. However,if it does not,there are various means the consumer may use to gain satisfaction.
The main idea of this paragraph is __________.
A.In person
B.Polite Consumers
C.Show Records
D.Store Manager
正确答案：C
答案解析：文章第一段讲述了大部分顾客买到假冒伪劣产品时首先会拿着保单或其他单据去要求退换或索赔，而这种方法通常是起到作用的。然后又说到如果这个方法不好使的话，还有其他办法。所以总体上这一段是介绍买到假冒伪劣产品时，首先要提供单据证明你的购买是真实的。
