> you would need to have a dozen people with clipboards strewn about the place
Assuming you live in the US, next time you're in a grocery store, count how many cameras you can spot. Then consider: these cameras could possibly have facial recognition software; these cameras could possibly have object recognition software; these cameras could possibly have software that tracks eye movements to see where people are looking.
Then wonder: do they have cameras in the parking lot? Maybe those cameras can read license plates to know which vehicles are coming and going. Any time I see any sort of news about information that can be retrieved from a photo, I assume that it will be done by many cameras at >1 Hertz in a handful of years.
I'm in Germany, so even if those places have cameras, they need to post a privacy notice describing what they do and how long they retain data. Sure, most people will not read this, but it's out there. I will make a mental note to read these privacy notices more often from now.
