Parking in Station Lane

I was sat in my car in a queue at the bottom of the lane waiting to turn right. An old guy drove up the other way and parked half on the pavement outside the opticians. A wagon following him struggled to pass and held up the traffic. The old guy was out of his car by now and I shouted over to him that he was causing an obstruction. He shouted back that he was picking up some glasses and told me to '' mind my own f**king business''.
