One of the most frequently asked questions of me by mystery shoppers is, "How can I be a better secret shopper?" My answer is simple, "Follow the directions." It seems simple, but you would be amazed at how many new mystery shoppers' reports are rejected because of missing or incomplete information.  Simple little things. Such as the name or the employee who assisted you, or seemingly minor details can cause a report not to be accepted by our client. The directions may also give you specific times you need to visit the location.  Perhaps there's direction as to how you should enter the store, where you should sit in the restaurant, etc.  These points are not there because they take up white space.  The directions are there because the client ask for them to be followed. So, my advice is to read the directions every time.  If you can't understand the direction given, ask questions. Oh yes, it's always better to do this a couple of days before you're going to do the assignment, not as you're entering the parking lot.
