All the casinos I've been to have given out free alcoholic beverages to all patrons as long as you gamble. Of course, people who were in an inadequate state due to alcohol were not there. However, a lot of people had with burning eyes from alcohol)
The fact that they are offering free alcoholic beverages, they can't assure that no one will get drunk, but as long as they behave based on the rules of the casino, I don't think there is a problem with that. When we get drunk, we are more aggressive, if we are lucky we could win but since most of the time gamblers loses, it will give them the advantage so that kind of trick really works.
The more that we get drunk is the more that we are positive and being that our bets will be continues thinking that every rounds will favor us.
until we realized that we have zero money in our pocket and we have no choice but to Go home.
Sad but true and this is the main reason why we are being treated like that from freebies for us to stay longer and lose more.
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.
