You'd be surprised how many people are out pulling scams on a daily basis, or I should say you'd be surprised if you've never worked in retail, banking, insurance, the service industries, law enforcement...
I know someone who worked at a bank. he/she decided it would be entertaining to steal a guys check, then take it home and wash and rewrite it. needless to say when all was said and done he/she got away with a few thousand dollars and they tried to accuse the guy who's check it was of taking the money. -via dadthinksomsaslut
Okay, so you're probably aware that many people are putting in work to pull off scams, and you may even know a few scammers, but let's not name names here...
When I was a kid my buddy and I kept a candy box from a school fundraiser. On the weekends we would go to the dollar store and buy candy bars for 3 for $1 and then go stand in front of Walmart and Target and sell the candy bars for $1 each saying they were for a school fundraiser. -Via moby323

I had a friend who worked at gamestop for a few years, and he devised a plan where, when new games were released, he would about once a day keep a receipt for a $60 game and just stick it in his pocket.
When someone would come in a few days later to trade in said game, he would give them the cash as a trade in (35-40 bucks I think) but not run it through the system. After the person had left and there was no one else in the store he would then run the game as a return, netting the retail $60 price.
He would then pocket the $20 difference, thus making himself an extra $80-$100 a week while the registers had complete paper trails and never appeared to be missing any dough. -via Huellio
