If you come to my restaurant isn't in my info that you walked in my door, sat at my table, ordered my food? Why do you think it's your info? When two interact both sides get to remember the interaction.
The question is whether you own information about their food choices that you can sell to a third party without even telling the customer it was collected.
On the one hand, it seems obvious that you have a right to observe, collect data, and sell it. On the other hand, ick.
Just ask TV and car manufacturers who collect telemetry about absolutely everything you do with their products and probably everything that happens on your connected phone and/or wifi network too.
Such things would use up the customer's (electrical) power for the company's profit in ways that were not intended by the purchaser. That is in addition to spying, which it also is.
The question is not if you can "remember" it. That is not what ownership in personal information is about.
The question is whether you can __sell__ the information that I had three double cheese burgers and extra greasy fries to my health insurance provider.
But if I walk into a franchise restaurant with a camera recording, they'll kick me out while happily recording and selling data with their own cameras.
