Would you prefer that Revenue and Customs just be disbanded ? Or would it be better if they only concentrated on people who clearly look a bit 'shady' and only travelling between London and Bogata ? Also, how do you know that people travelling between Birmingham and the Balearics are not involved in money laundering. Do you know that the Balearic Islands are one of largest drug consuming locations in western Europe ?
The reason different officers asked you the same questions was because when people lie they often make small mistakes when recounting their 'tale' You've obviously never been on an El Al flight.
I've been stopped by Customs officials on countless occasions, I've always been polite and answered their questions honestly without making smart arse comments.
