3 stripes is a senior first officer (Right hand seat)
And if he is positioning, he will be on these aircraft all the time.... so should know the safety card back to front.....
Out of courtesy he should at least put the magazine away, and at least appear to acknowledge the crew IMHO.
On another safety matter, how often do we as individuals walk around our cars and check the tyres, lights, and brakes before we trundle off down the road?
