Double dipping has come to mean getting more than your share, or getting paid twice for the same time or service. Someone who retires and then draws a pension, plus gets paid as a consultant related to their previous work is called a double-dipper. People who work on commission sometimes get paid for managing a client's account, and also get a commission for the buying or selling they do for the client. This is called double dipping and in some cases is unethical or illegal. In financial terms, double-dipping is when you get paid twice for the same work, get reimbursed twice for the same expense, or get paid twice from the same source (pension plus consulting). Example: Your employer sends you on a trip and pays for the expenses and then you deduct the cost of the travel as a business-related expense from your taxes - illegal!

His behavior was considered rude, unethical or immoral. George is called a double-dipper as a derogatory epithet. A fight ensued.
