A group of people are at a conference in a country house. Someone suggests hiring a bus to go out for a trip to a pub. Most of the group want to go.
It is 1953. Everyone goes and shares the cost.
It is 1973. Everyone shares the cost but the people who don't want to go stay behind.
It is 1993. Only the people going pay. Those who stay behind don't pay anything.
It is 2013. The people who don't want to go burst the tyres on the bus so no-one can go.
