Most banking analysts (read: first 2 years out of college) have similar need to have 'butts in seats' for ~ noon to maybe 4 pm. In the morning you have to finish the work you didn't finish last night or your boss wants redone, and you get more work around 4 or 5 when the older people start leaving. But there's a few hours midday where you have absolutely nothing to do except browse the internet or try to sneak off to the gym.
