If this was a one-off I would cut CB a lot more slack BUT when combined with the "verbal" assault reported by his mother and sister last year(what, did they disturb his concentration too, were they moving lights as the apologists for CB have said) then it paints a really bad picture.....to be honest, he comes across as an egotistical a-hole.
I don't think he's such an amazing actor that he's entitled to be arrogant and unpleasant to the "underlings" in his life.
