Wildeyedboy has a resourceful way of saving a buck at the airport:

At airports, I notice that a lot of people seem to perceive the "can't bring drinks past security" rule as a mandate that they buy expensive bottled water (or juice or whatever) inside. My resentment for disposable bottled water aside, I'd like to point out a rather simple tip. Security won't begrudge you an empty bottle. Bring it in, or if you have a full one, chug it and DON'T throw it away like I see so many do. Fill it at the water fountains at the terminal. Voila.
