MancRy,
The airline mentioned had a very relaxed attitude towards both safety and customer issues (despite an excellent safety record). I think the SCCM was trying to avoid the hassle of having another FA to show me the jacket.
And no it is not too easy to put a jacket even if you have look at the demo few minutes before. When I did try it I was not sure which side was front and which side was rear
.
As for the demo I am all in favor of having well endowed ladies doing the demo so the majority of the male pax would sit up and watch.
