I've seen the same principle at work in a pretty different activity: rock climbing. There's a well known story of one of the best climbers in the world getting approached by someone while she was tying the rope to her harness right before a climb. After a brief chat she proceeded to climb the route, lean back on the rope, and promptly plummet to the ground. After being interrupted she had forgotten to finish tying a knot she had done thousands of times before. It's a good reminder to avoid letting yourself get interrupted in the middle of simple but extremely critical tasks, it's just so easy for the brain to skip over part of the process it knows well and consider it done.
