If someone is hogging multiple slot machines, it's important to approach the situation calmly and respectfully. You can start by observing if the player is actively using all the machines or simply leaving them idle. If the machines are not in use and you feel comfortable, you might politely ask the player if they plan to use all of them or if they would be willing to share. If that approach doesn’t work or seems inappropriate, it's best to inform a casino staff member, who can intervene if necessary by reminding the player of the casino's policies on machine use.
