Who should be offered free alcoholic drinks at an event as per the text?

Offering free alcoholic drinks to any adult at an event is the most appropriate choice because it ensures fairness and inclusivity. Excluding only club members or participants in games may create a sense of exclusion among other attendees. Additionally, offering drinks to underage individuals is against the law and goes against responsible alcohol service practices. By offering free drinks to any adult, event organizers can promote a welcoming and inclusive atmosphere for all attendees.
