NOTE: This is another work-related experiment, something to do with your co-workers (from the Working For The Man book):
Why does office coffee leave such a bad taste in your mouth — a taste, which, of course, lasts for hours and takes a tooth brushing and five pieces of gum to fully get rid of? No doubt most of it has to do with the cheap ass coffee your company stocks the pantry with, as well as the old and abused and rarely cleaned machinery. But the human factor cannot be excluded. After all, your co-workers, the same people you regularly witness working at half-speed and churning out half-assed work, are the ones making the stuff.
Create a win-win for everyone in the office by holding a Best Cup of Coffee Contest. Assign each participant a morning of the week, and on their designated morning, participants are responsible for brewing the coffee — they can bring in their own coffee, or try to work magic with the coffee provided by the company. Offer up a rating system:
"Damn good cup of coffee" being a high rating, "Thanks for the all day bad breath" the lowest. Given that their name is tied to a specific morning’s pot of coffee, and no one wants to be associated in any way with bad breath, your co-workers will truly be inspired to achieve that "Damn good cup of coffee" level.
