JJ中的一道Argument，求思路

AA: Green Grocers has been experiencing high sales volume but decreasing profit margin.  Its customers are wealthy people looking for gourmet food and luxury shopping experience, so it must cut costs without hurting the customers' shopping experience. Therefore Green Grocers plans to lay off 10 employees and eliminate some expensive products and free sample. It will also partner with ** Cafe. Since according to a survey, the Grocers and the Cafe attract similar types of customers. As a consequence, Greentree Grocers will experience high sales volume and gain high profit margin.

看到这题有点不会动笔，麻烦大家帮我分析下其中的逻辑错误，谢谢！
