In high-stakes slot rooms, proper etiquette includes respecting other players' privacy, keeping noise levels down, and refraining from interrupting others during gameplay. It’s important to handle winnings and losses discreetly and to be courteous to staff and fellow players. Reserving machines appropriately, such as signaling when you’re taking a short break, is also considered polite. High-stakes environments often emphasize professionalism and respect, creating a more refined atmosphere.
