I have friends that work(ed) at William Morris in Bev Hills. Many usually do not hit the office until 10 am or after. I do not know KAs habits, but if he follows WMA, he might be a late riser.
I would suspect Benz is an early riser. I would guess he is a Johnathan Club member and goes to work out at 6am, just a guess as that is networking hour at the JC both downtown and Santa Monica.
So who knows how these two collaborate on a schedule.
