The conversation had moved to a "manager's voice" in a civilian setting after fireproof78's post, that's what I responded to.
But it doesn't even matter because I simply don't like how Brooks ready those lines. Should there be a difference in how he talks in private vs. how he talks at work? Yes, of course. But it doesn't mean I have to like the choices he makes for both voices equally. I generally like how he plays the father/friend/lover/husband Ben, I generally dislike how he plays commander/captain Sisko.
