Always pay attention during briefing. It is rude not to and you would be damned fool if you missed something.
You see, one thing that all passengers seem to not look at is what happens if their nearest Emergency Exit is blocked or unserviceable.
One always needs to check the next nearest, as well as the life jacket in place.
I also of long habit, always check and see if the the pax in the nearest EEs are drinking a lot of alcohol. Stupid neurosis? Perhaps, but I like to know who I have to help or maybe hysterical confused, deal with in emergency. Also, dangerous to say, but - always make mental assessment of cabin crew. Also check positions of fire extinguishers and smoke hoods. Not my job but I like to know.
So, is that arrogant? Perhaps, but the cabin crew are safer flying with me than with most!
(You can call that arrogant !)
