You Get What You Give
Once, there was a farmer who regularly sold butter to a baker
One day, the baker decided to weigh the butter to see if he was getting the exact amount that he asked for
He found out that he wasn't, so he took the farmer to court.
The judge asked the farmer if he uses any measure to weigh the butter
The farmer replied, “Your Honor, I'm primitive
I don't have a proper measure, but I do have a scale.”
The judge replied, “Then how do you weigh the butter?”
The farmer replied; “Your Honor, long before the baker started buying butter from me, I have been buying a pound loaf of bread from him
Every day, when the baker brings the bread, I put it on the scale and give him the same weight in butter
If anyone is to be blamed, it's the baker.”
Moral of the story: In life, you get what you give
Don't try to cheat others.
