Maybe the caller should explain that the dance in question will use hand to hand or link arms procedure. Can't really see why it should confuse the new to teh dance people, if the caller takes time to explain. I sometimes think that some callers do not allow for the beginners and concentrate on the more advanced dancers. I haver seen that occur and it does nothing to enhance the callers skills. All I saw was people complaining to each other that the caller wasn't very clear on what to do.
I have also seen quite a number of callers who take account of all levels.
