The Daily Mail (sorry) runs two stories on its front page today, written from two different perspectives. In the first, a pensioner has parked in the bay marked 'doctors only' at his local surgery, and is very upset when the doctor blocked him in for five hours. A complaint has been made to the General Medical Council.
In the second, an Audi driver parks across two spaces on a private driveway, and is blocked in by the person who has the right to use one of the spaces for two hours.
I've been in a situation where a person has parked at the entrance to our shared driveway and disappeared - neither I nor my neighbour could get our cars out to get to work, but as the car was on private property, the police wouldn't take any action. In the event, someone (may have been my neighbour or someone else) broke the car's window to release the hand brake and push it out of the way. When the owner returned, he was mightily irritated.
So, which camp are you in - make it difficult for the offending car's owner by blocking them in until a time of your choosing, or turn the other cheek?
