Looks like Jacob once again pulled-a-rishi, I did remind him about the daily standup meeting.
It's so common of pat to pull-a-rishi from time to time, even when we have important meetings.
We should fire the developer for pulling-a-rishi, it only because of his exceptional work that we continue working with him.
