Final answer:
An agent does not owe fiduciary duties to a customer, as these duties are owed only to clients or principals in a legal sense. Ethical duties identified by W.D. Ross, while important, do not equate to legal fiduciary obligations but suggest a level of moral responsibility.
Step-by-step explanation:
An agent does not generally owe fiduciary duties to a customer. In the field of law, the term fiduciary duties refers to a set of obligations one party, the fiduciary, owes to another, the principal. These duties traditionally include loyalty, care, disclosure, obedience, and accounting. These are owed to clients or principals, not to customers. A customer is generally considered as the third party with whom the agent interacts on behalf of the principal, and there is no fiduciary relationship established with a customer.
However, it's worth noting that ethics philosopher W.D. Ross identified certain moral duties such as duty of gratitude, duty of fidelity, duty of non-maleficence, amongst others. While these are moral obligations within general ethics, they are not equivalent to the legal concept of fiduciary duties in an agency/principal relationship. Nonetheless, in business and professional settings, agents should act ethically and responsibly toward customers.
