It's all in how you handle it. In a shop that was a reveal from the beginning, I talk to the manager first, tell them what happens if they pass, what happens if they fail. It is all in their own paperwork, it is required. But it takes the edge off of their anxiety.
If they miss a point, I ask them what they think. What I say goes, but they will be honest if it is really wrong.
I had to fail this sweet old thing today. I made sure he understood it was just one point too many, as I gave him his copy of the survey, and I went over his corrections book with him so he knew EXACTLY what to do. Yes, they could turn on me. and if I do this long enough one will bite me on the.... But a little compassion goes a long way.
But the funniest reveal shop I ever did was a large department store you have all been to. The first part was a mystery shop, then you contact the manager and go back and take some pictures (lots of pictures). Well my daughter and I didn't make it up the escalator, when people were coming up to us, "How are you? Can I help you?" I asked the manager for discretion, and it was as internally requested shop, but she had a pipeline to her people that was faster than the speed of light, "Auditor in the building." I'll bet she is a great manager, and my report reflected that. They were so sweet, but it reminded me of that scene in "Annie" where Daddy Warbucks comes home, and each of his employees in turn bow. It was amusing and a little startling at first. But of course, they would put forward their best foot. And I got outstanding pictures (I had already seen the small amount of "bad" stuff before they converged.)
You just have to love people; the boy with the nose ring (I can't even look at that) and the man with as many folds in his face as he has stories to tell. The young woman whose voice is so screechy it sends needles up your spine and the old curmudgeon that hasn't smiled since 1987, who has a trouble for each of his fingers each day.
But that is life. Maybe shopping just makes us notice. We certainly don't do it for the money. (smile)
