There ain't no such thing as a free lunch

"There ain't no such thing as a free lunch" (alternatively, "There is 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 acronyms TANSTAAFL, TINSTAAFL, and TNSTAAFL, 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.
