This is precisely why "going cashless" is silly. At least leave the option to those citizens that care about their privacy to be able to pay with cash and not be tracked the heck out of them.

Sure you can pay with cash. But you better turn off your phone because they also track you with your WiFi MAC address when you walk into stores.

Your phone should randomise the Mac when searching for access points.

That's where IOS did much better.

Does iOS randomize MAC addresses when looking for public wifi networks?

Another thing to worry about is whether iPhone really turns off the wifi radio when it is greeted out from the menu.. I remember a setting change somewhere around ios10/11..

And going all-cash, at this point, is futile. It's the same as the Google email or the Facebook profile conundrums. You can opt out, but they have enough context to infer most everything about your "hole" in their data anyway.
