Self service and attitude at CTIA

I commute to the Cape every week. I always check in online but can only get my boarding pass at the airport. The self service machines don't print out at this airport if you are checked in. I queued at the desk and asked Laduma who was managing the queue why the machines don't work. He just shrugged his shoulders and turned his back. When I asked again what I should do he said I should keep quiet and queue. This happened at 16:20 on 8 September and I was on MN 452
