This morning I was searching for vegan options for hide glue

I ended up in that page which I think it's a joke. So then I searched for that in Amazon.
This morning on my work computer I get this Dr. Jekyll thing provided to me by Microsoft's AI driven shit blaster.
You tell me WTF. My phone is not connected to my home computer and my work computer is not connected to either. How the fuck do they figure out the connection. And why? Like I totally I'm not interested in this particular story guy or even the fake glue that was the start of the joke.
yeah. I misread your comment. You're very right about that and Google has "wifi hotspots" to track users around NYC. https://theintercept.com/2018/09/08/linknyc-free-wifi-kiosks/
however, modern android iOS also have Mac address randomization on by default, so google has that data but I highly doubt random retailers do. Unless you install an app or connect to the network wherein they do the other fingerprinting I mentioned.
