Final answer:
Terminating services in order to pursue a social, financial, or sexual relationship with a client is unethical.
Step-by-step explanation:
Terminating services in order to pursue a social, financial, or sexual relationship with a client is unethical. It violates professional boundaries and can lead to conflicts of interest. In many jurisdictions, it may also be considered unprofessional conduct and result in disciplinary actions.
The excerpt provided in the question suggests that openly prostituting oneself involves accepting money and engaging in sexual activities with multiple people. However, the question is about terminating services with a single client for the purpose of starting a personal relationship, which is not the same as openly prostituting oneself but still considered unethical.
