Coffee Hour attendence

The graph below shows the number of people at a GraceDC coffee hour after church (recorded at 5 minute intervals).
It appears that coffee hour is most busy around the 15 minute mark.
Most people leave within 25 minutes.
Those remaining after 30 minutes are typically GraceDC members and they tend to leave coffee hour at a constant rate (linear slope).
