Honesty is the best policy

I know a person who worked in a Bank. I heard that person was fired because he made plagiarism. He worked as a cashier, every day when he finished his work he took one dollar from an account and he put that dollar in his account. He had more than one million dollars. He thought he was concealing that money but the Bank has a finely honed sistem to discover the cheaters. This gay lost his job and he also lost the money.
