In a kitchen, if more than one cook prepares the same dish, there is possibility of the dish being spoiled if all are allowed to have their say.
Everyone’s work is no one’s responsibility. Each person does the job the way he likes. The result is nothing but a big chaos.
To sum up, we can say that too many hands always create confusion. In a house with too many servants or masters, there will be no order. So, cooks in a kitchen, if too many, spoil the broth.
