Assume you are an accountant and is in charge of the cheque account for a small business. One morning, your supervisor, the accounting manager, enters your office and asks you to issue a cheque of $1,500 for expenses that he tells you he incurred entertaining a client last night. He submits receipts from a restaurant and lounge. Later, your supervisor's girlfriend stops by to pick him up for lunch, and you overhear her telling the receptionist what a great time she had at dinner and dancing with your supervisor the night before. What would you do and why?
