Really? Donuts seem like a pretty common office carry-in. At every place I've worked, someone would bring in donuts at least once a month. When I worked at a regional pizza chain, the morning shift would make donuts out of leftover pizza dough and dump chocolate syrup on them.

It feels like they are the quintessential breakfast food for feeding groups (much like pizza is). But maybe that's only a midwestern thing. But I'd be surprised because most major donut chains (Dunkin, Krispy Kreme, Tim Hortons), are not from here.
