There Ain't No Such Thing As A Free Lunch

"There ain't no such thing as a free lunch" (alternatively, "There's no such thing as a free lunch" or other variants) is a popular adage communicating the idea that it is impossible to get something for nothing. The initialisms TNSTAAFL, TANSTAAFL, and TINSTAAFL are also used. Uses of the phrase dating back to the 1930s and 1940s have been found, but the phrase's first appearance is unknown. The "free lunch" in the saying refers to the nineteenth century practice in American bars of offering a "free lunch" as a way to entice drinking customers. The phrase and the acronym are central to Robert Heinlein's 1966 science fiction novel The Moon is a Harsh Mistress, which popularized it. The free-market economist Milton Friedman also popularized the phrase by using it as the title of a 1975 book, and it often appears in economics textbooks; Campbell McConnell writes that the idea is "at the core of economics".

Famous quotes containing the words free and/or lunch:

    I will never accept that I got a free ride. It wasn’t free at all. My ancestors were brought here against their will. They were made to work and help build the country. I worked in the cotton fields from the age of seven. I worked in the laundry for twenty- three years. I worked for the national organization for nine years. I just retired from city government after twelve-and-a- half years.
    Johnnie Tillmon (b. 1926)

    Women who are devoted to causes, such as overpopulation and the underprivileged [sic], are much less interested in fashion than, let’s say, those who lunch at La Grenouille and Le Cirque.
    Ann Landers (b. 1918)
