Haha, intuition, the "Finnish" style is to only send a memo and think that world will be perfect and everybody follows a "supposedly clear instructions" in the said memo without any chance of communication perceived in an individually different manner
Well, then there are some of the bright FA's who know how to act, discard the memo details and take free liberty of excercising own style which my last flight male FA did and he was just great, with a smile! kudos to him.
