Some retailers hire companies to evaluate the quality of service in their stores; they often use mystery shoppers to get the information. They instruct a mystery shopper to make a particular purchase in a store or restaurant, and then report on the experience.

As a small business owner you want to know how well your business is functioning and
this is an inexpensive way to do that. Hire a company or someone to go into your place
of business and evaluate your staff for salesmanship, customer service, the overall
customer experience. Mystery shopping drives real improvement for future customers in areas
such as customer service, product selection, and cleanliness.
