The Sunk Cost Fallacy

"But you've invested so much time and money... you shouldn't..."

Jimmy McGill: "That’s the sunk cost fallacy, it’s what gambler’s do. Throw good money after bad. There’s no reward at the end of this game.”

Exactly how I always thought about paid food - money's already spent, whatever happens to the food - money's already spent. In many instances this is especially true for precious time spent.
