Final answer:
Service professionals should watch out for an inquisitive customer's excessive questioning and body language, while also being aware of their own nonverbal cues and staying congruent with organizational norms.
Step-by-step explanation:
Behavioral traits in inquisitive customers that service professionals should watch out for include excessive questioning that may indicate uncertainty or a desire for detailed understanding. A professional should also observe body language for signs of comfort or discomfort, such as avoiding eye contact or fidgeting, which can provide insights on how to better assist the customer. Additionally, they should pay attention to nonverbal cues they themselves project, ensuring they convey confidence and positive traits. It is important for service professionals to be curious and engage genuinely with customers, demonstrating a willingness to understand and address their needs. Moreover, being aware of and conforming to the unspoken norms and values in their organizational environment can enhance interactions with customers.
