You have to scan tags at Macy's because their pricing system and faux sales are so untrustworthy it's ridiculous. There's the tag price, which only someone in a desperate hurry would pay, and then there's the sale because it's Saturday, or Tuesday, or Leap Year, or whatever, plus the "Bonus Buy!" discount, and maybe another discount or two if the salesclerk feels like it.

I don't want to play that game, especially not in a restaurant. No prices on the menu, I'm out of there, and frankly I doubt refusing to put the price in writing is legal in most states, and I know failing to answer a customer's question about the price is illegal in any state I've lived in. Scan a QR code for the price? What game are they playing? Again, not happening for me.
