How much "legitimate" work do you get done in a day?

[Easy 6]

I work in sales, so its totally dependent on people coming in.

I've worked many a 12 hour shift & not talked to a soul... passing my time with crossword puzzles, newspapers, magazines, self-applied manicures & the like. Except, NO COMPUTERS! when the owner is around (5 1/2 days a week usually) ... he's SO old fashioned about that, i think he'd rather we literally jerk off on slow days than surf the web, or Planet.

Other days, i hardly have time to catch my breath... its kind of a feast or famine thing.
