Final answer:
Of the given options, leading conversations as the one with more knowledge would prevent James from continuing to strengthen relationships with his customers.
Step-by-step explanation:
Of the three options given, the characteristic that would prevent James from continuing to strengthen relationships with his customers is leading conversations as the one with more knowledge.
Listening is an important skill in building relationships. By spending his time listening, James can understand his customers' needs, concerns, and preferences better, which can help him tailor his approach and offerings to meet their expectations. This would strengthen the bond between James and his customers.
Tending to provide a level of trust with customers is another important characteristic for a successful negotiator like James. When customers trust James, they are more likely to engage in open and honest communication, which further strengthens the relationship.
However, leading conversations as the one with more knowledge can create a power dynamic and make the customers feel inferior or unheard. This diminishes the trust and rapport James has built with them, hindering the potential for further strengthening the relationships.
