What the Haribo?

When a gathering or activity which is stereotypically seen as “nerdy” is announced, why do they typically offer cookies as an incentive/bribe? Surely there is merit in their activity that does not warrant the offering of these baked goods? And also, which cookies are they? I would normally think of chocolate chip (the best kind of course), but if someone offered me raisin varieties or garibaldis, I’d rather go hungry! What if you’re allergic? You wouldn’t feel part of it when everyone’s scoffing the offending article in sight! Maybe the offering of an assortment is best – variety is the spice of life after all!
