How can someone be in a very bad mood, and the only thing that they could ever think of is to enter a casino, fund their account or walk into a physical one with their credit/debit card or cash at hand and want to pour their anger on the game they want to play? And the moment they experience losing, their anger will double compared to how it could have been. Some people learn how to control their emotions. In such a state, there are things to do and things not to do, and we will also never stop seeing such types of complaints around.
It sounds really crazy but it is funny how this is the exact thing some persons do in reality, they will go to the casino to "cool off" when they are mad at something or feel so angry but we know the truth remains that they only enjoy some adrenaline at that point that suppresses the anger for a while only to skyrocket it when they loose some more money to the casino. If you are sad, it is only an irony to wanting to get happy by going to a place where your chances of loosing money is high, on a normal day, when you are loosing you even get angry so I believe on a day like this it will be even worse.
One thing some people don't know is that no matter what mood you are in, especially when you are either having a bad day, family issue, monetary issue, etc., gambling can only distract you from that mood for a short time, but it can't solve the problem you are facing. The person needs to settle themselvesdown and get things solved instead of running into gambling all the time as if it's some kind of safe haven for them to escape their problem. Some gamblers need to be reoriented.
