: : Got a dialog between two officers:

: :
: : "A: Sobel's a genius. I had a headmaster just like him in prep school. I know the type.

: : B: Lewis, Michelangelo's a genius, Beethoven's a genius.

: : A: You know a man in this company who wouldn't double-time Currahee with a full pack just to piss in that guy's morning coffee?"

: : "to piss in that guy's morning coffee?" - is it some kind of idiom?

: To counter this practise Starbucks was born: now you have no idea whether anyone has pissed in your coffe or not, it just improves the flavor.

I don't know if that's an idiom. I've heard someone ask a grouchy person, "Who p**ed in your cornflakes?" Coffee would work too.
