If I'm not wrong it it is impolite to wear a hat inside,

(Take note Cathay staff you are beneath the non hat wearers)
Also unsafe to wear it during the walk around particularly during wind and I never stand around in public in a uniform so where do I wear it???
By the way I believe the new evac drill has a bendy stick with a flag on top for the captain, to be used in a evacuation as the locals when abroad will follow one blindly
