Not quite that drastic DS!
Although some passengers would deserve it; yesterday, after we had loaded 168 bags/skis onto a Grenoble flight, the news came through that 2 passengers has somehow lost their passports twixt chreck-in and the boarding gate - so they couldn't fly and we had to get their bags off. And that is a total pain in the arse as you have to unpack the holds to find the right ones, checking individual bags for the right name and sequence number. Invariably, they are always right at the back of the holds - never the first ones out.
And then you have to re-pack them all again. The Captains are always good though - they ensure the other passengers know the reason for the delayed departure and in TMR's world the responsible passengers would be taken to the side of the plane - in full view of the other passengers - and gently shot in the back of the head by us.
