Final answer:
Salespeople should regularly audit their customer service to avoid negative outcomes by gathering customer feedback, seeking expert advice, and performing root cause analysis to identify and address service-related problems.
Step-by-step explanation:
To avoid potential issues such as scolding from other passengers, decreased sales, and possible termination, salespeople should regularly audit their own customer service. This involves several key actions: gathering information from customers and other stakeholders, seeking expert information, and conducting a root cause analysis to determine underlying issues that may be affecting service quality.
Gathering information is crucial as it provides direct feedback from those who are affected by a salesperson's service. Seeking expert information allows salespeople to gain insights from those with more experience or specialized knowledge in customer service. Finally, root cause analysis helps pinpoint the exact causes of customer dissatisfaction, enabling salespeople to make informed decisions to improve their service.
