Sir, just shake hands with me in public; if my faith and integrity have any price, it is only this.

This couplet holds a sharp yet sorrowful mirror to human vanity and the desperate craving for social validation. The speaker tells someone in power that if their integrity has a price, it isn't wealth or gold, but simply the hollow pride of a handshake in full view of the crowd. It is a biting satire on how easily people compromise their core principles just to be publicly acknowledged by the powerful.
