Milk and bread.
Might as well throw in some potato chips too. lol
Oh heck, all food should be free....lol
Ninety percent of the people in Asia and Africa are lactose intolerant. I'm certain they would love to drink milk, instead of pure water...
Free health insurance, too.
Nothing is free for anyone but the air we breath. No matter what it is, somebody pays for it. If I were to name anything : healthcare, clean water as Zonk mentioned, food, etc..., somebody paid for it. That being said, if you receive free stuff you're leeching off of somebody else's hard work.
