Exxon/Mobil - because of the wreck of the Exxon Valdes (sp?). I was part of a team that put together and reprogrammed blood analyzers meant for humans to be used on the sea birds and mammals affected by the oil spill. It affected me deeply seeing how sick it made the animals.

Burger King - because I once got brown lettuce on a hamburger.

I don't really care about any given company's politics or policies. If you ask me, they're all crooked.
