It seems that the message has sunk in with the general public that joking about bombs to airport security people, although amusing, is unwise.
The lastest twist on the story, however, features some unfortunate chap joking about bombs with his mate on the plane, and some exceptionally jobsworthy cabin crewpersons overhearing this and reporting it as a Serious Terrorist Incident.
Remember, when you’re on an aeroplane, you are entirely subject to the whims of the humourless minimum-waged morons who provide you what’s laughably referred to as ‘in-flight service’. As with security guards, nightclub bouncers, and other people who have nothing going for them other than the ability to make things rubbish for those with less miserable lives, it’s best not to fuck with them.
