Final answer:
Ethos refers to the ethical appeal that portrays a person as trustworthy and credible, an important aspect in business for building customer relationships.
Step-by-step explanation:
The expected performance that sends a message of being trustworthy and honest and having the intent to provide quality service is known as ethos. Ethos is the ethical appeal that suggests the writer or the speaker is credible and reliable. In a business context, it is crucial for building relationships with customers and clients. Ethos can be communicated through consistent honesty, integrity, and professionalism. In performance terms, an actor imbues their character with ethos by consistently portraying intentions that reveal the character's trustworthy nature, even if they, as an actor, know the outcome may not be successful. The quality of service is underpinned by this commitment to trustworthiness and integrity, laying the groundwork for positive customer perceptions and experiences.
