I agree. When I compare AC to the other airlines I've flown I'd put them in the middle of the pack for quality and consistency of service. Of all the potential reasons to choose one airline over another the consistency of cabin service is pretty low on my list.

Flight attendants aren't waitresses. What I sometimes wonder when flying certain Asian airlines is whether the tiny, extraordinarily polite woman in a cheongsam or ao dai who served my dinner will be a help or a hindrance in an emergency.

I'd rather AC focus on that aspect of FA training instead attempting to mollify fussy passengers who are tallying up the number of pleases and thank-yous per segment. YMMV.
