In Red Eye, Lisa just met Jackson at airport. actually he is complete stranger to her. At drinks corner, Jackson's guess nearly came close what Lisa going to order for drink:
Lisa: It's an impressive talent, though. Very close.
Jackson: You know, breaks the ice.
I know "Breaks the ice" is idiom which means two strange persons getting relaxed each other, but here context is totally different to used it, he just guess her drink.
