Human nature is weak
Keep a watch on your servants, but do not be tyrannical in doing so. Do not put temptation in their way by leaving money around: human nature is so weak ! Take note of what they spend on your behalf - particularly cooks. Do not take the view that they are out to cheat you, but be aware that they can make mistakes.
Never scold your servants in front of strangers; this is bad manners to your friends or guests who will not know how to react.
One last piece of advice.
A girl must not play with a servant girl, nor listen to her; she will give orders only if authorized to do so by her parents.
