Working out of a Starbucks for a little bit (yes with a VPN). I'm not signed into any Google services with my default browser (Safari 12 on Mojave). Not signed into the Starbucks website either.

How do they know who I am? How am I on some list now? And what list? I didn't check a box, sign up for anything, or otherwise identify myself. WTF.


@chartier in addition to your Wi-Fi MAC address, they could have cookies on your web browser (even not being logged in), i think those pages are web pages and have access to cookies.
