I'm not serving yet (6 more months), but I keep a similar tradition in my office . Anyone who leaves their things where they shouldn't be, gets it shrinkwrapped multiple times. Then I use heavy packing tape and tape the offending items to a wall or column with their name written on it in large sharpie letters for all to see.
Items shrinkwrapped include: Glasses, sunglasses, folders, pens, wallets, cd cases, coffee cups, toolkits, pizza in a pizza box, and entire lunch from Wendy's (I thought about trying to wrap each fry individually, but decided it would take far too long)
