If there's one thing that every office has, it's coffee politics. There are a lot of things to say and a lot of decisions to be made when it comes to the office's coffee supply. That's why we believe in coffee co-existence, and this person is a proponent of that too. Look at this; he devised a way to let his colleagues know the office brew's freshness so that no one has to suffer through a single sip of old coffee.
And his methods are so simple, too; all he did was take two styrofoam cups of coffee and make a neat, adjustable freshness gauge with them. Now, if only it were automatic.
