It's always been for me, that whenever an employee suspects I might be an MSer (not because of anything I've done, but because of something the shop requirements call for lol)....you can almost see a lightbulb go off and the employee suddenly jumps into their cheeriest, most helpful self.
Not today, lol.
Right as I took what I hoped to be a nonchalant photo of the meat slicer, I saw a person in management garb suddenly bend down and whisper something in the cashier's ear. He smiled at me. She gave me a grumpy side eye.
Oh well, not so good for you. LOL.
The MSC has to expect this, no matter how low key the shopper is.
