Yep, exactly what Dom said. Not to mention the chances of them coming back to my site is next to zero if the casino offers them a sweeter bonus than I can.
Especially to any gambling whales that might show up. Re-read Engineers post.
If you were a high-roller and you go to the casino via a casino junket, and the owner of the casino comes up to you and says, — forget the junket — I can get you a much sweeter deal if we work directly, clearly the person will go with the casino owner.
edited to add: and no junket in his/her right mind would be bringing any more high rollers into that casino – they’d be scared this crazy casino owner was going to snake them all…. clearly a predatory move in our biz
