Trust me, the behaviour in the noisy office borders on gluttony (the Lead Nurse calls it Team Diabetes!) and can eventually put you off even free goodies. You should come visit us for a week, it'd help a lot. Imagine every bad habit you have repeated multiple times and amplified by echoes. (you should visit anyway! I need you to yell at all the IT departments)
But I still took some and am rationing them out, personally I don't think complete denial works. If you're allowed a little bit every now and then it doesn't feel like such a hardship.
