Great initiative and hopefully you see people that have gambling problems flock your website to get your help or get help for someone, gambling problem and gambling addiction is often overlooked by some as not that bad kind of addiction but let me tell you that it's as bad as those other ones when it's ignored and not treated.
I mean. It is not a secret that the point of getting drinks to gamblers in the casino while they wager is to get rid of more of their inhibitions. It does not only works with money or gambling, it also works for people to better socialize and forget about their problems, that is the reason you can find shy people who act in a very different manner when they start to drink alcohol. It has happened to me personally.
I can attest to the inhibitions part, that's what one of my Science teacher told us back then about alcohol, that it relaxes or weakens our inhibitions and another thing that we should also remember is that alcohol doesn't change someone, it just releases the repressed personality that they've got behind their sober persona so if you have a loud personality but you're generally, you'll be a loud one when you're drunk and you're aware of it most of the time. Me supporting the claim with my experience isn't a thing that's going to make this the absolute truth though as there's no study presented and only personal account that's similar to what happened to you.
Anyways, back to gambling and money. If we depart from the fact gambling is supposed to be a recreational activity and one should never step into a casino with more money than one is willing to lose, then I do not see much problem when comes to drinking alcohol while gambling, provably the average gamblers would have lost the enterity of their budget regardless they were drinking or not. A different situation would be to step into a casino and drinki while one has access to credit cards, much cash or valuable objects, in the worst case scenario, one could wake up in the next morning with debt and without the valuables one had ar the previous night. There is where the actual danger or the combination of gambling and alcohol lies on.
The first one is what's likely to happen and it's a smart thing that an individual is like that but the second situation, it's a problem both for the casino and the individual, the reason for that is that a casino should be taking care of their players so they shouldn't allow them to get to the point of blacking out because of drunkenness and with the individual, you should've been street smart about the fact that someone's going to steal money from you if they can so it's your responsibility that you're not going to let your guard down and that you're safe with your gambling experience.
