The employee was fired last March after she sold a hamburger to a co-worker who then asked for cheese, which she added.
McDonald's argued this turned the hamburger into a cheeseburger, and she should have charged more.
They also said, she had broken staff rules prohibiting free gifts to family, friends or colleagues.
But Leeuwarden district court ruled a written warning would have been the best way to have handled this.
The court also stated, "The dismissal was too severe a measure. It is just a slice of cheese."
It ordered McDonald's to pay the worker the salary for the remaining five months of her contract - a total of 4,265 euros ($5.976.55)
McDonald's was also told to pay court costs.
So, now the cheeseburger cost McDonald's over $6.000 dollars, but what do they care?, they maintained discipline.
