The expression "There's no such thing as a free lunch" means that even if something appears to be free, there are always costs involved, whether they are immediately apparent or not. In the case of a free lunch, the resources used to produce it (such as the cook's time, the ingredients, and the energy used to cook it) are not available for use elsewhere. Therefore, there is always a cost to producing and consuming anything, regardless of whether money changes hands.
