Really, its much easier than you think. In those auto machines you load tickets, when you work in a store where 5+ people are in the machine daily, he would load tickets, and tear off from say 3-24 on the 20’s. Then once a customer would come in and purchase those three the machine shows ---- meaning the tickets need reinserted. He would go and load the tickets. Once the remaining 6 would sell, he would repeat. The store I was in had a 24 facing. So about 3 (20), 4 (10), and 6 (5) were in there. This happened in the matter of two weeks. The checkbook bounced from +12k to -10k. With no real money coming in, and tickets going out that seemed legit no one caught on. Now had he stole a whole pack its a different story.
