If an argument arises at the blackjack table, it’s important to remain calm and composed. First, avoid escalating the situation by refraining from taking sides or contributing to the conflict. Instead, focus on listening to both parties to understand their perspectives. If necessary, involve the dealer or floor manager, as they are trained to handle disputes and can help mediate the situation. It's essential to prioritize a respectful and friendly environment, as arguments can disrupt the game and negatively affect everyone at the table.
