Dog has discriminating taste

We are having relatively nice weather. I was sitting out today and was reading. Suddenly I hear a lapping noise and see my dad reach for the camera. The dog was drinking my iced coffee. I stopped him (it is not good for dogs) but he followed me when I moved the cup out of his reach (I know - dogs are not supposed to drink coffee). He wanted to drink more! I gave him fresh water (which he promptly snubbed). I guess the dog has discriminating taste. ;p   For the record he was drinking my Guaremala Santa Isabel Single Estate Espresso that I was drinking as iced coffee.
