Pre-booked?
Terry K Rumble
Obviously I was not there so did not hear what was said, but, the pre booked may not relate to online check in / seat selection. It may be that the passengers have had a connecting flight and been checked in hours before on another leg of their journey - something I have benefited from before.
However that still does not explain why unsuitable passengers were in the seats.
On a lo-co, into STN a couple of years ago I was shocked to see one of two middle age ladies in the exit row, across the aisle from me, use a walking stick to help her down the aisle after we landed.
I do look out for this sort of thing now, I'm glad to say I have not seen it since however.
