Found outside the ARTery some morning later in the week and shoved into our office and forgotten about until teardown:
A plug-in shaving device, an ipod with charger, some keys on a ring, an Xmas stocking that says Nick on it that had change in the bottom of it (Santa sap? Naughty!).
If it's yours, you'll be able to tell me the colour of the iPod and the type of thing these would have all been found in. iPod doesn't have any contact details, but the music's pretty good, we listened to it all the way home- thanks!
