The security system in the UK is one of the worst there is. Each and every airport has pages of worthless rules enforced by humourless, wretched "jobsworths." Their job is to pick up where Osama left off and make our our lives unpleasant. Your immediate response should be a "Yes sir, of course, how stupid of me!" and comply. The next step is to complain to your MP and the Minister for Transport - it's his bunch of morons who dream up this sh1te.
