Bring a reusable, stainless-steel coffee thermos to your regular barista the next time you fill up on a skim latte with an extra shot. Some stores will even give you a discount for bringing the thermos. Added bonus? Your hot drink stays hot longer, and because most coffee mugs are designed to be spill-proof, you won't splatter that mocha latte all over your shirt.
Tip: Store hot macaroni and cheese in a thermos to enjoy a warm lunch at work.
