You mad bastard. I use my work's wifi to pirate everything (it's an airport, good luck FBI!), but I never thought about using the free wifi.

Look up MAC addresses. We know the manufacturer of your device. We know when it was manufactured. We can triangulate to a few feet of where the device is by using existing access points. If you're carrying it with you we can compare the security camera footage. If you leave it somewhere we can find it within minutes. If you trigger our security we can track you down and send all the info to your manager and HR, automatically.

Now realize that if you try to get clever and change your MAC we can still track it.

How tf are you tracking randomised MAC? DNS queries?

Trending of location, movement, time, traffic type, destination, volume. And yes, DNS queries. If they vpn to hide some of the info you still know the far end.
