I wish I was making this up but his happened to me one time.
My briefing:
Me: River Visual 19 speed are set Vr, V2, Vt for X lbs, plan a right turn off at foxtrot no hot spots to our gate, if we go missed I will go down the river or what tower tells us to do.
CA: Are you going to build it in the FMS?
Me: No
CA: So are you going to be using white or green needles?
Me: None it is a Visual
CA: So how are you going to know if you are doing it right?
Me: I am going to look out the window.
CA: Do you mind if I build it just to feel better?
Me: knock yourself out
He then spent the next 5 minutes building the damn thing in the FMS.
Now in his defense, he was a DFW guy that had never been to DCA outside of the sim.
