Dear Cerberus and MR8,
I totally agree with "staying there and making sure things are ok". This question was asked of me some time after the event, and I was not present at the time of the incident. I can assure both of you that had I been present and privy to the situation I would have had AS on the phone, regardless of the hour.
I put this forward on this forum simply to make others aware, and to encourage consideration of the "what would I do in that situation" scenario.
Off to work now......CTOAN
