Sneakers41-That is so true. Every mystery shopper thinks that everyone knows that they are a mystery shopper when they first start out because they are very self conscious. The best thing to do is to read the scenario a few days before your shop and actually visualize yourself conducting the shop.
Then after you actually complete the shop write down as much information as you can remember in your car about the exchange and write it up when you get home. Always remember the name of the person you dealt with and what they looked like.
You would be surprised how quickly you forget what they looked like when you get home. Also, always keep the phone number of the company handy in case you run into a problem. Sometimes locations are closed, or if you are shopping an event representative they may not have shown up so you can not evaluate them.
It is also important never to reveal to anyone that you are a mystery shopper. The shop and all of the information regarding it is highly confidential and should never be revealed to anyone.
