It’s always good down to the last drop.
That is, until the bundle of ice keeping “the last drop” cool decides it hates your face. And then it shoots down your glass like an Olympic luger, SMACK! directly into your eyes and thus blinding you, clanging into your teeth and chipping away at them, straight up your nose and into your brain.
That may be dramatic (read: completely accurate), but nevertheless, our ice is out to get us.
