I don't spin my dice, but I fiddle with things. I'm not at all bored and I'm playing close attention.
However, in my career, multi-tasking is an absolute necessity. I have done it for so long and so extensively, that...I just can't stop. I am almost incapable of sitting there and doing one thing.
So, I've given up trying. I listen, take in what's going on, pay attention and enjoy it...but I do so while fiddling with my dice, reading obscure rules, etc.
So, in other words, as long as I am confident that I have someone's attention, I don't care if I have their attention while they are also doing something else.
