Why do people insist on waiting for arrivals on conference calls? I'd get it if they were key players, but when they're not, why have 10 people wait even 5 minutes for someone to arrive? You just wasted the equivalent of 50 minutes. Start on time and don't recap for one person, you're still wasting time at that point. Same thing for onsite meetings, be on time and don't wait. That was the reason you set the meeting time, be prepared.
Can you tell I wasted much needed time today in meetings/conference calls? :).
