And from a local's point of view....
For the past x number of years (since the pub was built), successive landlords have been happy to allow locals and others to use the pub car park, on the basis that although the person might not be a pub customer at that particular moment in time, the chances are that they will be a customer at some other point. In particular, residents of the houses on Main St/High St knew that if they came home and found all the on street parking taken up by visitors, there would always be the pub car park. Another vital service to the local community was the landlord(s) allowing people to use the pub car park when going to the surgery, which is opposite the pub and has no parking of its own.
When the current landlord arrived about a year ago, the landlords of the other pubs went to introduce themselves and welcome him to the village. They were told 'I'm not here to be friends, I'm here to put you out of business'. A few weeks later, my husband parked on the car park and was threatened with violence if he did so again. Next thing, all the anti-parking signs appeared. Needless to say, half of the village are now boycotting the pub.
