When I was a young child 8-9 years old we as a family would play poker (usually 5 card stud) at Christmas as we always received some money as gifts maybe 1$ or $2 and we would play a cash game my brother, father, uncle, grandfather, and best friend. As I remember in the end my uncle would always take the money. The adults drank a lot and my brother and I got to act like grownups and have a glass of beer. This was back in the 60's. Probably not acceptable today.
