Brewing my own coffee at work. It's immeasurably better than the floor sweeping they provide at the break cubby.
I bring my own coffee from home every day. And for when that cup is done, I brought a Tassimo into the office and make myself my second (and sometimes third) cup using that.
The company provides coffee/tea/hot chocolate/water at no cost to the employees. But the coffee they buy is cheap crappy stuff. Tassimo brewed coffee may not be the best stuff out there but it's better than the crap the company buys.
