I walked through the park at lunchtime. There were a group of 5 men (late 20s early 30s) with a handful of kids between them aged c. 18m-9years. They were kicking a football around and the men all had a can of Fosters in hand, with a crate alongside for refils. They were maybe a bit loud, but weren't being any bother to anyone, but it still made me judge .
Really though, they were outdoors playing with their DCs (good), why was it different to if they'd been having lunch in a beer garden, or having a BBQ at home
