Here's a story from BBC:
BBC News - McDonald's 'wrong' to fire worker over cheese slice
What was right in this circumstance, and is this a matter that the courts should involve themselves with?
A McDonald's outlet in the Netherlands was wrong to sack an employee for giving a colleague a piece of cheese on a hamburger, a court has ruled.
The waitress was fired last March after she sold a hamburger to a co-worker who then asked for cheese, which she added.
The fast-food chain argued this turned the hamburger into a cheeseburger, and so she should have charged more.
But Leeuwarden district court ruled a written warning would have been more appropriate.
McDonald's was ordered to pay the former employee more than 4,200 euros ($5,900; £3,660) for the last five months of her contract.
