Something acquired without due effort or cost. For example, In politics there is no free lunch; every favor calls for repayment. This expression alludes to the custom of taverns offering food free of charge to induce customers to buy drinks. It was soon extended to other kinds of gift but is often used in a negative way, as in the example. [First half of 1800s]

A gift or benefit for which no return is expected. This expression, dating from the early 1800s, alludes to the practice of taverns offering free food to their customers to induce them to buy more drinks. In today’s bars such offerings amount to little more than a bowl of peanuts or pretzels, if that, and indeed, figuratively the term is often used in a negative context—for example, “He’ll hardly offer you a job if you don’t contribute to his party; there’s no free lunch in political campaigns.” The economist Milton Friedman went even further, declaring “There’s no such thing as a free lunch” (attributed).
