I think in general this particular station is perceived as a low risk area.
Lots of bikes have their lights left on (on the bikes, not witched on) all day. A fair few have their computers left on too. One chap leaves his spd shoes in a bag hung over the handlebars (not locked).
Friendly security staff do keep a regular eye on things, and they know most of the regular commuters, so they *might* notice anything nefarious
But I'm afraid I'm not that trusting! Regardless of whether it's the tip bike or the swanky cross bike, everything not fixed down gets removed, a D-lock through the frame, back wheel and Sheffield stand, a cable lock through the front wheel and Sheffield stand, and if there's a Brooks on the bike it gets covered with a plastic bag!
