It's not like we try to fill the 30 mins, but I think we all crave a little connection with our colleagues, so make use of the time to catch up. I've worked with these same team members for over 3 years, so we are all a little invested in each others' lives by now. Obviously I'm not going to force a new team member to divulge everything about their lives, or go through my weekend in detail unless they're actually interested in chatting. It's pretty clear when someone just wants to get on with their work, rather than chat.
