well in real life I boycotted BP and a lot of other people did too and that didn't really matter too much because most people just buy gas when they need it or where it is cheapest. So they would take a smaller hit than they did anyhow. It wasn't 75 million dollars either, they paid $20.8 billion under threat of government force.
