Never worked in a call center before...?

I used to be a server, and serving is a breeze to me, so much so i got bored with it and hated the wage, so i got hired out at a call center as a technical support rep. I know my way around a computer like the back of my hand so that's not a problem for me, it's just the whole cubicle, headset, phones, and stapler 8hr a day environment that frightened me a bit. The cubicles are tiny, people try to decorate theirs but it makes it look more depressing and more crammed, and they are all squeezed into a big warehouse size building. All of them, in rows and columns with their headsets on and slouched over. How do you people do this 8 hours a day???
