My GLO started etiquette lessons at our conclave 2 years ago...At first I was not impressed because Lunch took us 3 hours to eat and the woman teaching it was a bit snobbish (one comment that I and many others disagreed with was that one is not supposed to acknowledge or thank the servers at a banquet)
But overall it is helpful, so now once a year(usually founder's day) the division goes through etiquette lessons (but much quicker). Each chapter was also provided with enough booklets for each sister that describe situations and show diagrams of silverware.
So, if your sisters need it, go ahead and teach it...it is always nice to be able to go out for a nice dinner and know you are not making a fool of yourself.
