This of course presumes that your service is within the bonds an honourable master would request. Dishonour can be earned for many reasons, including reasons for which an honourable vassal cannot turn away.
For example: A man may promise his child's hand in marriage to another, but the child may not keep that promise and choose another. The man is dishonoured by his inability to keep his promise, but in no way is he a less worthy man. His public honour is impacted, but his personal honour is intact.
In fact, one can argue that a vassal who has promised service is not able to withdraw that service until given permission from their liege (or their liege's liege). Ironically, only an honourable liege would properly release their vassals from service in the event that their honour was sullied.
