RESTAURANT RESEARCH SCENARIO
Insight Research, a marketing research company, has been hired by a national chain of family restaurants to help them better understand their customers and their preferences. The restaurant chain has several competitors competing for the same customer segments and has experienced sales declines in the past few years. Researchers go "under cover" and pretend to be customers so that they will fit in while they observe the interactions between customers and the wait staff. Subsequently, they write a report of their interpretations of what they experienced personally while pretending to be a customer. They also add in details of what they saw regarding interactions of other customers with each other and with the employees of the restaurant. Some conclusions drawn were that the employees were not especially attentive to the customers and that customers were overheard saying they didn't intend to return. Some researchers also noted that the food was not very good and they saw several customers return orders.
