This thread is hilarious. There have been 71 posts. Yet no-one has just done a simple "say this" approach briefing for the plate in question!!!!
Yes, but if you read those 71+ posts you will see why? Your example contains too many "XXX's" to be relevant other than as a template. The thread originator should have a grasp of the template already, from his own company procedures and acquired experience. The thread has evolved into a discussion on the usefulness and relevance of these briefings.
It wasn't that the point was missed, it was rather a case of what was the point? If the poster had asked for an example of your inflight PA to the passengers, it would have been much the same. There would have been as many different versions as there were people who replied.
