I got caught at Blackpool too! Was on a X country with a female colleague. We landed at Blackpool walked through the gate out to the terminal had a cup of tea then paid the landing fee (what a rip off) then got directed to the departure gate to get back airside! Oh Oh! alarm bells wrang I had my usual pocket full of spare odds and sods including my small Swiss army knife, which I purchased in the duty free at Geneva airport, when I saw the metal detector and Xray machine my heart sank. Sure enough a jobsworth tried to confiscate it and when I started to argue he was about to call security, fearing an arrest and all the ensuing hassle I gave in and reasoned with him which resulted in a lecture and being told to leave it in the aircraft. Story over! Wrong! We then flew to Teeside went through the gate guess what! repeat the last part of the story! Oh I do hate Jobsworths!!!
