Wait. So, like a person interrupts you?

The thing in my city? It's like this, but each 5~10 minutes. Each time it's a different person advertising something else. It's frequent enough that you can't hold a decent conversation, even if your only "mistake" was to sit on a bench in a public space. If you ignore the advertiser, they'll insist and use a slightly louder tone, as if you were assumed to be deaf; and if you ask them to leave you alone [even politely] they'll babble about "trying to help you so you don't miss this amazing opportunity".

Just to give you an idea: once, my then girlfriend and me decided to count it. We sit on a bench, drinking some booze, and we got twelve advertisers bugging us in a hour and half. Including: eyeglasses stores, phone providers advertising "number portability", local popular restaurants, handcrafted accessories sellers, gold buyers, so goes on.

It's basically an offline example of the same thing that happens on the internet. Everybody and their dog wants your attention, and they'll make sure to be heard against your will. The text doesn't directly acknowledge that, but note how everything there ties it to advertisers, from "S.E.O. hackers have ruined the trick of adding “Reddit” to searches to find human-generated answers" (why? For ad views!) to Tiktok "pushes us to scroll through another dozen videos of cooking demonstrations or funny animals" (why? Ad views.)

Not comment OP, but I assume its similar to mine. People will approach you to give you flyers of their buisness, free samples, or otherwise smooth talk you to enter their shop/stand.
