For me it's the blenders that drive me insane. I don't mind some background chatter and often listen to music anyway, but those damn blenders cut through earpieces and drive me a bit mad.

Still, I do enjoy it from time to time as a change of pace. Mostly I've started working at our local co-working place in Rochester - unlimited coffee, no worries about leaving your laptop if you need to run an errand, etc.
