“There’s no such thing as a free lunch” is the proverb that reminds us nothing is truly free. Here is what it means, where it comes from, how to use it, and a few sayings that share its hard-headed wisdom.
What Does “There’s No Such Thing as a Free Lunch” Mean?
The proverb means that you can never really get something for nothing — whatever seems free always has a hidden cost, paid by someone, somewhere, somehow. Even a genuine gift or a generous offer usually carries an obligation, a catch, or a price built in elsewhere. It is a favourite of economists, who use it to explain that every choice has an opportunity cost: choosing one thing always means giving up another.
Origin of the Proverb
The phrase comes from a real American custom. In the nineteenth and early twentieth centuries, saloons and bars offered a “free lunch” to anyone who bought a drink — but the food was deliberately salty, so customers grew thirsty and bought far more drink than the meal was worth. The lunch, in other words, was never really free. The saying in its modern sense appeared by the 1930s, and was made famous by the science-fiction writer Robert Heinlein in his 1966 novel The Moon Is a Harsh Mistress and by the economist Milton Friedman, who used it as a book title in 1975.
