Utterly brainless idiots!
I regret to say that UK "airport security" defies any common sense, logic, common courtesy and usual fails to enhance security.
It is a job creation plan for the otherwise unemployable run by half wits who could not get a job with the elf & safety.
They are on an ego trip the size of a planet just because anyone who questions there actions is instantly inconvenienced beyond all reason and treated like a criminal, They are also judge and jury in all matters so even polite complaint via the official channels will be brushed aside even if they acknowledge the communication in the first place.
My advice is to avoid these half witted egomaniacs at all costs as it is imposable to reason with these people simply because they don't have the intelligence to engage in an adult conversation.
Without doubt the UK security is the worst run in the world and reflects the government's attitude to the citizens of the UK and is just the tip of the iceberg that includes ID cards and Internet snooping.
By now you might have guessed that I don't like these people!
