I used to work down the road from a big tourist attraction in London. Every lunch hour, I’d need to walk past a mass of people congregating outside the building taking photos, among other things (like forming a circle around a busker, taking up even more space).
I could try wait for a dozen people to finish taking photos (and it’s never just one photo, selfie or otherwise).
Or, after a couple weeks of this, I just stopped caring and would walk past them irrespective of interrupting someones shot. Now if they made an effort to leave an easily navigable gap behind the photographer so I could walk past without interrupting, sure, I did that. Most didn’t.
There’s still a lingering uncomfortability knowing I might be recorded forever in someone’s social media feed or whatever they do with the photos. Yes I know, it’s a public space and all.
