My brother neighbor got a pergola build and bloke next door took it on to ask council to go and check if they had a permit. Council just said it was a random door knock. They moved 6 months later.
Same bloke has had words with my brother regarding his HG big block chev. It was on idle for a while while he was doing some stuff with it during the day on a Sunday. Apparently he was dying from the fumes in his house.
