Obviously the kids that were there had no idea that it could be reserved. See another comment here about that reservation being available only on an app, not the website.

The cluelessness is in the aggressive assertion of their "rights" and their complete failure to listen to what the local kids were saying. Hell, they couldn't even be bothered to play a pickup game with them.

The frightened / annoyed looks of the two Dropboxers when they realized they were on video adds to the hilarity. I was pretty sure they wanted to be cops asserting some bogus right not to be filmed in a public space at that moment.
