Was that an Flight Leader trying to get the Safety Video to play? It seems that scene is reenacted ever time they board the jet, they block the entrance, get frustrated, say it does not work and then finally the FO shows them how to press the button that looks like |> and .... magic! They don't have to do the demo

Departure City, Arrival City, Flight Time ... it just aint that hard.

Trivia question. What happens next:

Option A: FA thanks First Officer for assistance with the system (which the FA should know how to operate) with a happy gesture and smile, or
Option B: FA continues grumbling about how the now operative system does not work, while slamming doors, grazing on half eaten food and complaining about passengers boarding the jet
