I got bounced for one of the world's worst behaved manager and employees/bad food to boot shop. It was on a Sunday, no less-and MSC had bonused up to $25 for the fee alone. Not at all my part of town, but I felt sorry for the scheduler and took it.
Suffice to say that if most of those employees had been working for me, they would not have a job any longer. If it was not a shop, I would have left the building without ordering or eating. However, I soldiered on.
The person seated next to me began complaining very loudly about the food he was served, the "burger" seriously looked like a sausage patty. He engaged his wife, then me, in conversation and was very insulting in his remarks. The manager came over to shut him up and re-served the food.
After I reported the entire incident along with the rest of the mess, the manager fingered me as the shopper, but claimed that *I* was the difficult customer and was commenting about my food to the other couple. I dared the MSC to roll that video to prove it. They paid for the bonused shop, but took me off the client.
I can't say I wasn't warned. The instructions state explicitly that the target looks for mystery shoppers diligently and tries to "catch" them.
