Regardless of the experience of the professional pax., the crew had no option but to continue for the full 30 mins. Whether or not this is the correct course of action is not for me to discuss. Hopefully the people within BA will look into it and reassess the guidelines. Can you imagine, however, the furore if the crew had stopped before 30 mins - there would be legal action left, right, and centre. The crew followed the guideline to the letter.
With regard to my resignation from the Union and my request to see the documents - I believe that there are many on here who are not in the Union yet would like to read the documents. Thanks to the many people who mailed me the link.
