I've never travelled through Manchester. But I travel a lot, and what I do is simply to grab a bunch of trays, and add all my gadgets (and camera, if I have one) from the bag and put them on a tray. Including the little Kindle. There's no point wasting time asking. Sometimes (b/c this depends on the local rules of the country, and they change too) the security will notice and say 'no need, keep the camera in the bag', but if not, it does no harm. I don't remove my shoes unless there's a sign saying that I must. As my shoes don't have any metal in them there's never a problem. But I always wear simple shoes that I can just flip off in a moment, without bending down, just in case.
