Question Author
Thanks to all for your responses so far. The reason I am asking is that I own (franchise) a few food restaurants that are a national chain (Subway). As franchisees we have to pay for mystery shops to be performed every month in our stores, the customers often do not seem to complete these correctly and I am wondering what use they are in relation to the kind of business we provide. Obviously they are a good pointer to service in general, but I feel the main problem is that as soon as a customer comes into the store as a mystery shopper, their whole perception changes as they know that the real reason is not to shop, but to judge the service and this makes it very difficult for them to give a real and accurate answer.
Sometimes we get responses from shoppers where their perception of the service they should have received is completely removed from reality of a business that pays minimum wage to staff and provides a sandwich starting from £1.99.
Once again thank you for your thoughts, I would still be interested to hear any further ones.
