I would like to post something in response to skymaid80's comments.
I tend to spend most of my time up front, but do wind up in coach on about 2 out of 10 flights. And I, too, have noticed how very infrequently people in FC thank the FAs for their work. But I have also notice about the same percentage of thanklessness in coach. I don't know why this is, and would not care to speculate.
But, like blairvanhorn, I always thank them and try to be appreciative; they have a difficult, difficult (and too often thankless) job.
To all the good and wonderful and caring FAs: Thanks for everything!!!!
