Dude, this kind of thing is everywhere in Europe. It’s rare in the US, but it still exists in some places. People love being outside. Just because you’re always indoors doesn’t mean everyone likes that. I go to breweries often, and as long as it’s not incredibly hot or cold outdoor seating is the first thing taken.

The US has been constructed so this kind of thing doesn’t exist in most places, but where it does it’ll always be occupied.

It looks like a Google Street view shot to me
