Stop in for a cup of coffee

Sounds very good.
Hopefully he has no second thoughts and starts testing you bit by bit. You know how people like that can be.
My perspective at this point is that it will be like training a dog. He tries to test me and I will slap him back hard, reminding him of who is in charge.

Besides, the best thing he can do to me is to fire me from my perspective...and the worst from his.
