You might want to read up on that. Start with George Washington. He and his family had people stopping by their farm (a lot). They were treated as guests and fed and housed.
"In the true tradition of hospitality, the Washington's welcomed hundreds of guests to Mount Vernon each year. Many of the guests remained over night, or for several days, and the servants were kept busy preparing rooms for visitors. Mrs. Washington kept low post beds in storage that could be brought down and set up in the rooms to accommodate the overflow of travelers." - Mount Vernon
