Brand loyalty. We're all vets. Is there a brand of something that you were introduced to that you'll go out of your way to support?

WWII vets loved their brand of cigarettes that were in their C-Rats. Viet Nam vets seem to love their Budweiser beer that was provided to them.

In 2004 while deployed to OIF I was given free coffee from Seattle's Best and Starbucks and became a coffee snob. I won't drink that Green Beans coffee if I was paid for it. What brands do you love and/or hate from your time in service?
