Depends who the second person is. And of course we are in an age where companies pride themselves into hovering up as much "public" data as they can find, analyze it and sell it to whoever wants it, so "find every photo or video this face is in" could lead to quite a detailed profile depending on how often this happens. Scale matters.
(Similarly to how "we have license plates on cars to identify them if needed" is a thing and basically nobody complains that I can see your license plate when I walk past your car or write it down if needed, but thousands or millions of cameras recording all traffic and logging plates are something people are concerned about, even if its completely legal in some places)
What was that Larry Ellison quote that came up again over the weekend?
EDIT: or to bring a specific real-world example: A friend of mine does classes at a local studio that also offers martial arts courses, and some of the local right-wing bubble has gotten it in their head that this has to be "antifa combat training" and keeps screaming that this needs to be monitored. The current local government has been ignoring them, but a lot of people are probably quite happy now that there isn't an easy-to-get public record of who was there and "needs a visit" just because some influencer needed to film her dance lessons.
So your specific real world example is that nothing happened, but IF somebody had filmed them then you IMAGINE they would have "gotten a visit". Very specific and real world.
