8. Cash
If it's by mistake or a byproduct of a guilty conscience is up for debate. Still, quite a few workers have discovered substantial sums of cash lying in trash collection bins, with some instances being tens of thousands of dollars in the sum.
One respondent said that while he was a full-time student working at a movie theater, he found $5,000 in cash. The honest employee turned in the money, but no one ever returned to retrieve the money. Another staff member reportedly said he found $3,000 in cash tied together in the rubber band.
