I assumed that Vader used the Force to somehow absord the bolts as he knew what a fast draw Han was. He had the drop on the galaxy's biggest badass-thus was prepared to take away the blaster. Han gets off quite a few shots though. I don't really think Vader was expecting quite that speed.

I do love the fact that Vader just toys with Han-he could easily have taken away the blaster earlier.

"Does anyone have a straw so I could eat? I'm kinda hungry..."

"What if he chokes on the brussel sprouts? He's worth a lot to me." "The Empire will not compensate you if he dies of natural causes."

If the scene existed, I envision a sligtly awkward meal that is reminiscent of Dr. No. "Tell me Vader, does the crushing of all freedoms really compensate for having a computerized James Earl Jones in your vocoder?"
