Each person behaves differently in a state of strong alcohol intoxication. Someone becomes more relaxed and sociable, someone falls asleep, someone loses control and becomes very generous, and there are those who become very aggressive and can start a row if they lose.
However, I have never seen such people in a casino. Perhaps the security guards control the process and do not allow such people to get drunk.
That's why there is security and CCTVs, to remove those people that are not thinking straight anymore. They want to avoid the mess as much as possible and not bother those players. Because if a fight or trouble escalates, that will be a loss on their side. Casinos don't want that as much as possible. The show must go on.
This means that the casino security services do it very efficiently or skillfully. I have never seen a very drunk person taken out of the hall. I only once saw a person who reacted aggressively to a big loss being taken out, but he was sober.
