Real estate professionals are confronted by rude people everyday in all kinds of situations, but when faced with dealing with rude people during a real estate transaction or negotiation, this dysfunctional, even abusive behavior can threaten the very success of the transaction at hand.
During moments like that, every real estate professional will benefit by remembering that nothing will be gained by engaging with rude people who are acting out from an internal source of insecurity and distorted need to be in control. Rude people tend to treat others bady or act out in inappropriate ways in order to hide their lack of self confidence and personal power. Stay the course, remember you're the professional in the room, and stay focused on the end result rather than the momentary "winning." No one wins in a battle based on abuse, egos or insecurity.
