Or anyone who doesn’t want to be tracked by random retailers. I worked for one such company, so I know intimately how it works, including how MAC address randomization doesn’t actually work in the real world at completely obscuring your device.

Would you mind sharing the details of how MAC address randomization is being defeated in the real world?

@pmontra already provided you with one good link, let me know if you'd like more info. Happy to share peer reviewed articles as well as what I can from the work I did.

Does this work even if my device newer connects to the retailer's "free" WiFi?

It makes it trivially simple if you did connect, but even if you don’t, just having the Wi-Fi radio on is enough.

As long as the wifi radio is enabled, yes.
