Your tasty beverage is warm, so what do you do? Reach into the freezer and grab an ice-cube or three. Plonk. Swirl. Cold again. But, as you circulate through the crowd, body-heat warms your drink. The ice melts, and you're left again with a warm, and now watered-down, beverage. This is neither stylish nor efficient.
