You have a co-worker — let’s just call him Bob — he comes into the office early, and sees someone had just started a pot of coffee maybe two minutes before him. He stands there, waiting a few seconds, then thinks … I’m in a hurry.
Bob pulls the pot out from under the dribbling coffee stream, and fills his coffee cup from what there is in the pot, then puts the pot back under the stream. He walks away, whistling, with an extra strong cup of coffee to start his day.
Bob just stole the heart of the coffee. The rest of it is going to taste like crap.
Don’t do that, Bob! It’s a sin! You have sinned against coffee!
Bad, Bob! Bad! No no!
If you see Bob do this, roll up a newspaper and smack him.
