Final answer:
Staff who can deliver great customer service are identified by their interaction with customers, professional demeanor, and commitment to service; assessing irrelevant factors is not helpful in identifying such staff.
Step-by-step explanation:
Ways to identify staff who can deliver prompt, friendly, and courteous customer service include observing their interactions with customers, assessing their ability to maintain a professional appearance and treat everyone with respect, and evaluating their commitment to providing excellent customer service. However, one method that would not be effective in identifying such staff would be to assess something irrelevant to customer service abilities, such as ignoring typos or irrelevant parts of questions. Focus when identifying good customer service staff should be on their actions that directly relate to service quality, such as their punctuality, appearance, respectfulness, focus, task completion, and support for the company's overall goals.
