For years I never had to make coffee in the office...someone else already started a pot!
Many years ago (before prepackaged servings) I had to come in to work very early, so being the first in the office, decided to try my hand at making coffee.
Never saw anyone else do it, so I simply inserted the filter, grabbed the can of Folgers, and filled the filter up to the brim and pressed the "brew" button.
Man!
The whole department wondered who made the rocket fuel that morning!
