In a surprising twist, the new full body scanner technology has proved reliable in detecting which travelling Leprechauns are carrying gold coins on their persons.
Airport screeners have already reaped a tidy sum by telling the Little People that the coins must remain behind at the baggage check-in with the nail clippers and scissors.
When the Leprechauns complain, security officials generally point to the short time remaining to catch their flight and hand them a lengthy claims form that no one ever fills out, anyway.
If the complaining persists, they are threatened with their clay pipes being checked for illicit substances.
This usually sends them on their way.
British officials see this as a way to reclaim at least some of the gold Gordon Brown sold so cheaply a decade ago.
