Usually if it doesn’t belong there, it’s crap.
But sometimes there’s an exception to the rule.
I didn’t check if there was something in it (you’re not supposed to touch anything 😉 ).
But if you recognize it, and you believe it’s yours, write me a line (with distinct details, that are not in the picture, so I know it’s really yours 😀 ), and I’ll try to find it again when I go down next time 😉
