Those are all folding/portable chairs, not fixed chairs. There are a few fixed benches built into the sidewalk in front of a few houses in my neighborhood, and 5 would apply to them. I'm also curious how this could be interpreted for someone who is merely a renter and not the private property owner.

edit: LOL they edited it out in response to my comment. There was a photo of a circle of folding chairs between the first selfie and the pancake party photo: https://i.imgur.com/Ygd8Of6.png
