TopBunk - I have less than your 20 years experience but I have had a serious problem that the CC noticed first. Consider yourself lucky my friend but please don't dismiss CC input.
If you have that opinion you're probably going to give off those vibes when someone from the cabin calls to report something. If they go away with the feeling that you don't take them seriously are they likely to think highly or less highly of you?
Cabin crew are much more touchy feely / perceptive people than those of us on the dirty side of the locked door!
