You live in a small town where shopping needs are well met by local shops and a large supermarket chain wants to put a store in town despite the objections of 80% of the population. On principle you too are against the proposal and decide that, if it does eventuate, you would not use the new store. When the campaign was on and commitments avowed, a local was heard to say, ‘Given time, principle will succumb to convenience!’
The townspeople lose the battle and the new store is established.
Will your principle stand the test of time especially if, at some time, the new store has something you want and it is not available elsewhere in town?
