No one has mentioned the much more important topic.
That is passengers simply taking the trouble and reading the name on the tag and addressing CC by their name. I always do this and it does seem sometimes to initially startle CC but they then seem to really appreciate it and I'm certain that we receive that little bit extra friendliness as a result. Banter is much easier if their name is used.^
I am always worried about being thought a dirty old man if I peer hard at the name badge of a well endowed member of the CC! That's my story and I am sticking to it!
