Ever get a message from Walmart asking you to rate something you bought—when you paid cash and didn’t even have your phone on you? One shopper did, and it’s got people talking about just how much stores know about us. The buzz is that facial recognition and other sneaky tech might be tracking us, even when we think we’re off the grid. Next time you shop, remember: privacy might cost more than your receipt shows! #Business #LocalBusiness #Walmart
