[knifeandfork]

i host a poker game where i provide food and drink and deal the game i charge nothing to participate, the game is in a private home in virginia. the players tip me. can big brother construe this as a poker gmae spread as a business? is it illegal, and if so why ? thoughtful answers appreciated. i have glanced over the law and not found any reason why it would be. thanks in advance.
