Airline crews have lost run of themselves
Airline crews in particular seem affected with many of them turning into overbearing martinets at the slightest ‘provocation’.
Along with a cranking up of levels of fear, anti-terrorism strategies seem to be having the opposite effect of what they were supposed to. Where aircrews are concerned it seems to have become an excuse for staff to transfer frustrations onto passengers. I would suggest crews take their gripes up with their bosses and try and remember passengers are the reason they have jobs in the first place.
