I hope you realize that grocery stores track you in other ways than just your zip code or phone number [1]. You have a beacon in your pocket that is always searching for SSIDs or Bluetooth IDs, which is more than enough to uniquely ID you. You can combine that with facial rec now and link a face, sex and estimated age to the SSID combo. Who names their phone “<Your name>’s iPhone”? They can get your name too.
If you truly wanted to be paranoid, set your device to airplane mode (don’t forget your smartwatch or wallet Tile), cover your face (this shouldn’t be hard these days) and only then venture into a store. Oh, and pay your groceries with cash.
