You’ve obviously never met my mother. You give her an unfamiliar mechanical device, and she’ll stare at it, totally perplexed, maybe smack it or shake it, but mostly, she won’t have a clue what to do. I never understood this about her - she’s actually quite intelligent, but unfamiliar devices reduce her to an ape-like state of beating stuff with a rock.
But she does know how to operate an airline seatbelt, having flown a few times in her life.
And as for the OP - the safety announcements are such a small part of the flight, whether they’re dry, clever, or insipid, they’re over in a minute or two, so who cares? Personally, I enjoy the unconventional approach.
