Here's a situation. You're sitting in a restaurant and the owner rewards you with free food for being the first customer to arrive. You feel delighted that you don't have to pay for anything. You eat and eat without even thinking. You try something and if you don't like it, you throw it away since you're not paying for it. But don't you realize that it is still being paid for by someone? The owner paid the cook to shop for the ingredients. The grocery store where the cook bought the ingredients bought those stuff from a certain company. And that certain company paid farmers to plant and harvest those food from them. That company paid another company for the packaging of their food. And that company paid a hundred workers to do that work.
The "free" food sitting infront of you is being paid for by everyone else. It went through an expensive process to get there. It started with a farmer, a company, another company, a grocery shop, then a restaurant. Each and every one of them paid for it. so don't go wasting it if you don't like it because somebody out there is working their butts off for you to have that food. And if they knew you just threw it away, it would mean their work was for nothing. Appreciate everything you have because it came from someone else's sweat. Don't waste it.
