Variation on a theme...
wipneus goes to a bar:
— Ice?
— No, thanks, I'd rather have single–malt with a 15% ice coverage.
wipneus goes to a bar:
Bartender: Ice?
wipneus: No, thanks, I'd like it ice-free.
Bartender: There you are, sir.
wipneus: Excuse me, bartender, but these look like ice fragments in my drink.
Bartender: It is, sir, however I think you'll find that there are fewer than 1 million square decamicrometres with greater than 15% coverage. That's an ice-free drink, sir.
