Know more about Speke Hall than LJL, but this caught my eye:
but this bollocks about asking every pasenger 'the questions' is ridiculous. They should be part of the terms and conditions of baggage acceptance - what's someone going to say, "Yes someone could have interfered with it"??
Except who reads the terms and conditions? Well, maybe those who take enough interest to hang around PPRuNe, and then most of the time in a desultory sort of way. Average punter, especially the knuckle dragging end of the market? Get real. The questions are an essential part of life, and one day might just prompt a "well, actually..." type response. Just chill out and view the questions as sort of checklist type item.
