You may be (un)pleasantly surprised by the amount of physical/real-world tracking of in-store traffic that stores are engaging in now. In many physical stores, you don't really have the option of "'browsing' without them already tracking me" either. Worse yet, there's not even a pretense of viewing/accept some Terms and Conditions when you physically enter the store (at least websites pay the lip service of having a T&C posted or a cookie consent pop-up).

One random example from 2018 (so, probably a lot more advanced and widespread by now): https://www.adweek.com/digital/adobes-newest-labs-project-ca...
