The hospital where I worked suddenly decided that as the parking was being used by locals for town shopping or parking for near by offices they would charge. So visitors got a cheap rate and staff had to buy a permit. These of course were very limited, staff had to park at the furthest places, and eventually they offered parking about a mile from the hospital with a bus to bring staff in. But of course the managers, consultants etc. all got their allocated parking spaces. Even those that only came in 2 days a week.
