Assming that you have the airline right, to be honest, I don't think standards of service have slipped, not by my experience, anyway.
CC are always polite, and attentive, in fact very often overly so, in a nice kind of way, but then again, I've gone from Blue to Gold this year, so maybe thats why the're being nice to me.
As for the knob in row 1, why express his view of the "unbelivalbe airline, why am I not suprised ?" at the poor CC, only trying to do her job, and as for the old couple sitting behind me, as stated, she was still on the phone to a call centre, asking for the messenger sevice number to put in her phone as we lined up. I lost my rag by then, as I said and asked what made them special, and not liable to obey a legitimate instrucion.
Rant rant, it's good for my BP, apparently.
