Mixed Nuts

I took a much-needed Luddite Day yesterday, shutting down the computer and spending the afternoon loafing on the couch reading. I had meant to have a new stereo installed in my car and do some Christmas shopping while I waited, but we got a moderately significant snowstorm yesterday afternoon, so I pushed the installation and shopping back to today, rather than waiting for the roads to get really bad and then trying to come home from the mall.

This means I’ll be spending today doing some Christmas shopping while my car stereo is upgraded. So it’ll be a day of open threads, a serious one to come a bit later, and this frivolous question:

People who go through a bowl of mixed nuts and pick out all the cashews and almonds leaving just peanuts behind are:
a) Evil heretics who should be flayed and scourged.
b) Totally sensible, and hey, could you re-fill this? All the cashews are gone.

Be sure to show your work. For extra credit, extend this to the case of people who eat all the nuts and pretzels out of a bowl of Chex Mix
