replying to west8 above
i only recently noticed that some bookings were not marked as confirmed just scheduled and was a bit suspicous the booking might fall through, fortunately it did not.
have since paid more attention and noticed this often happens, saw both HTF + Mel (not together!) and neither changed the status afterwards despite it being a good meeting.
So i guess if busy and they have lots of positive feedback they're not so concerned to change the status.
Geeky stuff - the word "completed" is in a string of text and could just as easily be e.g. finished/fulfilled ... whereas the status of the booking is one of two codes
within the database, it might well be a simple letter or number 0 = requested, 1 = scheduled, 2 = complete.
