Completely different context.
No, you're guilty of the same thing you accused Karnak of.
If I wanted realism, I'd wake up at 4am and possibly force down some powdered eggs and bitter coffee. Follow that with a mission briefing with a queasy stomach feeling when the target is revealed, followed by hours of boredom and a few minutes of sheer terror. Realism isn't going to exist in the MA, it just isn't the place for it. Changing the game settings to even attempt to do so is akin to the legendary task of Sisyphus.
What you are talking about sounds more like a scenario event, and belongs there. On the days of an event, I'll purposefully drink lousy coffee (which isn't easy with a Keurig machine) and have an egg before the frame starts. If I have free time, I'll even put my Glenn Miller records on the player while I wait. However, I wouldn't expect anyone else to do this before a frame, and even I wouldn't do it for a routine MA experience.
