That is part of it I guess, there is no entertainment if you don't spend money. And casino's are the perfect example of it. You play let's say in a land base casino, the moment you step it, adrenaline is already rushing, you see lots of people playing winning big and then some live bands performing, drinks everywhere. And so you are suckered into that energy, you lost control of everything, endorphins shoot up in your body and you are 'high' and wanted to gamble your money.
