I have a suspition that casinos that offer a very high percentage 30-40% pay no more than casinos paying 15-20%. A % of what. They are offering a percentage of net revenue, but how do they arrive at this net revenue figure? Unless casinos state in their contract what net revenue is then it can be any thing they want. A casino may offer 40% commission but they may also adjust the net so that you are only being payed 20%. Has anyone noticed a 20% increase form a casino offering 40% and one offering 20%? I havn't. :-?
