The cashier of the Easy Company intercepted Customer A’s check payable to the company in the amount of $ 500 and deposited it in a bank account that was part of the company petty cash fund, of which he was custodian. He then drew a $ 500 check on the petty cash fund bank account payable to himself, signed it, and cashed it.
