Meaningful conflict wasn't always easy for Jon Taffer, the star of "Bar Rescue," who is known for confrontation and resolution on the reality TV show. Taffer talks to Salon's D. Watkins about his book "The Power of Conflict: Speak Your Mind and Get the Results You Want" and what he's learned over the years from fights and heated moments that ended poorly. "'Bar Rescue' taught me the whole premise of meaningful conflict," Taffer said.
