I was doing a shop for a fast food establishment where I had to park and be served. I was near the front in order to get the best view of comings and goings. I could see through a glass door, a giant white board for employees to reference. Written in HUGE letters.. it said "ONE MYSTERY SHOP REMAINING". I thought hmm.. I must be that one last shop. I couldn't help but giggle about it.
I did a grocery store recently where the deli clerk told me all about the things she needed to make certain to do because the mystery shopper was coming today (no idea how they knew but I did report her conversation.)
