When facing aggressive dealers in Blackjack, it's important to maintain a calm and composed demeanor to avoid escalating tension. Players should focus on their strategy, avoid emotional reactions, and stick to their game plan regardless of the dealer’s attitude. Setting personal boundaries and knowing when to walk away can also help prevent negative interactions. If the behavior persists, politely addressing the issue with the dealer or requesting a change of table or dealer through casino staff can help restore a more comfortable playing environment.
