I once had a temp have a similar "personal item" delivered to the office after she'd finished working for us. Due to the nature of her role the package was assumed to be work supplies. Fair play, though: she returned to claim her parcel!
I left my dildo in the loo at work. HR sent a company wide message, with a photo of the travel bag I keep him in, asking the owner to retrieve their "personal item". I'll miss him, but there's no way in hell I'm going to go and get him back from HRs desk in our open-plan office.
