Greed have been the major factor that leads gamblers into this kind of situation and in this case, both the gambler and the agent are greedy in their different ways, because both of them are culprits in all this and for them to reach such an agreement and settle to bet in credits, it means that this is not first time this is happening and if truly so it then means that this will not also be the last time either because this is a Normal way of operating the business because their want to make a real sale by all means.
I think the same, I have always disagreed with the idea of casinos being allowed to extend credit to their clients, if we were talking about a real estate agency or a car shop then it would make sense those businesses could do so as what they are selling is too expensive for the majority of the people out there, however a casino only sells entertainment and as such they should not be allowed to use such tactics which take advantage of those which do not understand their games.
