I am one of the working class, who spends almost the whole day working.
I wake up early in the morning to prepare for work. I don't eat much for breakfast, which is the most important meal of the day to have.
I just usually have a cup of coffee, then I am on my way. I make my coffee using a five-cup coffee maker, but I just consume one cup.
The rest goes cold and wasted. Upon realizing what I am wasting, I bought myself a single cup coffee machine.
So every morning, its always an exact one cup, no more no less and no more waste.
