A mate parked in them, one of the residents parked right up to his back bumper blocking him in (he wasn't even fishing just popped along for 10 mins) next thing Mr Angry comes barging out of one of the houses kicks off and police get involved at which point we have it confirmed that the 'residents only' signs have about as much legal standing as a wet paper bag (apparently the residents put the signs up BUT the council is looking at sorting something propa).
