One thing I am very sure of is that, casinos that care about there users will sure do all they can to protect their users and also give them the very best services they can offer, but they(the casino) must figure out a way to do this that it won't affect their finance, finance is the major factor/aspect of running a casino successfully, because, if the casino treat the customers so well in every other aspect, but fail to pay the customers winnings due to lack of fund, the customer will still scream, wail and call the casino a scam and a cheat.
This is why I think casinos do as much as they can to gather funds, in other to never to have to tell their customer that the reason they can't pay the winning immediately is because the lack fund, I believe if a friend tells you that a casino has not paid his winning because they lack fund, you will do all you can to stay away from such casino.
Personally, to say they lack funds I don't think so at all, because they have a lot of capital, and also if we compare it to the number of losses of each user I believe the number of losses of each user will be greater than the number of wins. So to say they're understaffed and I think that is preposterous nonsense.
I'm sure when they set up a gambling site, they have really considered what will happen, and in the beginning they can even spend a lot of money for a promotion from their site. Unless from the start they had no intention of paying and intended to make things difficult for users.
