Alan, good guide knows when to lead softly and when to lead loudly. Both are required at time but always with tact, respect and understanding. Students should always know you care but also know you mean business. The balance can be difficult but following up with explanations that get into the details of how time is critical and wasted time is time away from their learning of the class materials often drills home the importance of your course policies and the reasons for your actions.
