"Your obedient servant" is an old formal expression used to show respect and deference to someone you are addressing, such as a superior, a customer, or someone you want to impress. It is usually written at the end of a letter or email, and is a polite way of saying that you are eager to serve or help the person. However, this expression is not commonly used in everyday conversation, and it is mostly used in formal or business settings.
