Lick it up or guzzle it down?

If it's there and it's fresh, either will do, though it wouldn't be right to refuse to drink a health to the guy who thoughtfully put it into a glass for you, (is all that his?) and means that not a drop is wasted. Licking the glass out after gulping it down would, of course, be obligatory. Looks tempting, doesn't it? - all that manly protein!
