Hedging your compliments against embarrashment is a pretty sound and wide-spread strategy though. Varying levels of experience and 'special fellow obliviousness complicate the matter, but ideally, either party knows that "beatiful eyes" and "have coffee" has more than one meaning. If they don't react to the sub-text you can at least claim that it was never about that anyway, saving face in the process.
You know, I think we deserve a robot apocalypse.
