Consider this for a moment: Whether they know or think you are a shopper should have absolutely ZERO impact on how the employee behaves. It does, but it shouldn't. Asking if you are a shopper, or saying they know you are a shopper is pretty much telling their employer, "Hey, I'm done working here." Companies don't give out bonuses to the employee who spots the most shoppers. And by companies, I'm referring to the level where decisions to hire mystery shoppers are made, not individual stores and managers.
I have worked retail jobs where training specifically covers what to do if you think customer is mystery shopping and it was basically, "Keep doing your job." When an employee asks if you're a mystery shopper, that tells their employer that they are not providing a consistent level of service, and is important information for them. Our job, as stated in practically every shop guideline or training, is not to reveal ourselves. I don't consider saying, "No, what's that?" any more of a lie that saying I'm interested in buying a new refrigerator or whatever.
