Not for poor people, those better situated would eat it more often. More importantly, people were not eating just steaks, but all parts of animals, so (in case of my grandparents in Yugoslavia) they'd eat a chicken or pork on Sundays and holidays, but on other days they'd perhaps have a cooked meat and bone marrow from a soup, or fried liver, or stew made from Sunday's leftovers. Also eggs, milk, cheese and other dairy products, that were affordable to everyone.
