Getting free drinks in the casino has been their business model for a long time. Already in the 1970-80s casinos would give their customers free drinks and even full cigarette packs to have a good time. Back in the day everybody was smoking in doors and the air must have been really bad. Hard to imagine today how the environment was back then, also people where drinking much more than they are today. Getting drunk and gambling is a common combination in Las Vegas, I still remember my first time visiting the big casino and the atmosphere of all the drunk people gambling. If this only happens once a year during a vacation I think it's fine and people should be enjoying themselves, just make sure you have fixed limits to gamble with and better to rely on cash for the time you are there and leave the bank cards at home. The problem is of course if the occasional visit becomes to regular behaviour. Personally I rarely drink when gambling, one or two beers is fine but nothing stronger. Another factor that could lead to addictive gambling behaviour is to always think about gambling, even when we are not even playing or on our way to visit a casino. Spending too much time thinking about new strategies and possible winnings we could make, is not a good idea. Our brain will become used to these thoughts and this will lead to much higher gambling activity than is good for us. In my opinion we should always have fixed rules and boundaries when it comes to gambling so we don't spend too much time on it.
