platform is already full of tragic, planespotting c**ts jealously guarding their spots and tutting loudly should you dare to stand in front of them. Occasionally, one with a camera will attempt to remonstrate with you that you're obscuring his line of sight, at which point you point out to them that the great joy of aeroplanes is that they do what's interesting in the sky and that, unless I suddenly grow to ten times my actual height, I am unlikely to prevent him seeing the flying machines. Should he continue to grumble, I find a cheery 'Piss off!' does the trick.
