I still have all my name tags, some loaner ones I honestly forgot to return and two ID's. They never asked for any of these things back both times I quit. When I rehired back in two years after I quit they knew I still had the ID and just reactivated the old one.
And TheDude, you really have a twisted mind! I would have never thought of that. Is this a 'one who smelled it dealt it' kind of thing??
