lol i did keep it in my office at but i hate mixing stuff there, spills, powder dusting up the keyboard and desk and bringing back cups of water, ect .... I thought that it was convenient to do it in the kitchen and it was....now i must reconsider....
when i worked at a big place, i kept it all at my cubicle. I'd bring in a 2 liter of diet dr pepper, my shaker, and food. I'd keep a tub of powder at my desk or in my car. The only reason I got up was to get ice from their freezer for my soda, to microwave things, or to get water from the watercooler. I found it was inconvenient to prep/keep food at my cubicle, but sure beat dealing with dirty, clumsy, selfish idiots who used the community kitchen.
Then again, I was an anti-social prick too. Ate lunch at my cubicle. I tend to hate most people, blathering about their life drama or American idol. I went back to my cubicle and did homework at lunch.
