Always reminds me of a holiday trip I made with some mates back in the 1970's, at the time of the Troubles, to the Channel Islands from Birmingham Airport. The flight was called and we were ushered through the usual channels, where we were pulled to one side and asked to open our luggage. Security then went everything with an extremely fine toothcomb, piling everything up on the table and rooting through it.
When it was eventually repacked and we were given the all clear to continue, I did remark to one of the security people "Blimey, that was a bit excessive, we're only going to flippin' Jersey".
"Oh sorry," he replied, "we thought you were the tail end of the Belfast flight!"
