Family food obsessions

Does anyone’s family obsess of over a certain food? My fiancé’s whole family LOVES olives. lol it’s weird. Not one of them dislikes olives. I went to a family dinner with his dad, aunts, uncles, cousins and grandparents and they had so may different variations of olives lol. Olive bread, olive soup, olives in a bowl, casserole with olives, olive dip. It was just crazy lol
