It wasn't appropriate for the man (Craig) who lost the money gambling in one night because the gambling firm are doing their best to prevent addiction and the last time I checked their promotion is not much to the extent of it not been fair.
If the online casino could called him to check up on him after he lost £20,000 in one night it mean they really care about their customers well being, it Craig that ought to have sought for help when he's going on the verge of addiction, not after the issue is worse.
I believe it the thought of making money through gambling that causes his addiction.
