“So, like, we’re in this place called a pub. And what pubs do is they own a building, and in that building they sell beer and other alcoholic beverages, and in return for buying the beer and other alcoholic beverages they let people stay, for free, in the building that they own. And from the money they make from selling their beer and other alcoholic beverages, the pub gets to keep their building and the people who bought the beer and other alcoholic beverages get to have fun, and everyone lives happily ever after.”
