I worked about 5 years in Oklahoma at Various Casinos, the last few years as a card room manager. My girlfriend is now the Table games manager at a Casino up on the Northern boarder.
In the poker rooms it's pretty common for the casino to make 2 drops during a hand, the $4 rake on the right and the $1 player promotion on the left. The player promotion money is the players money not the Casinos. This money is to be used for promotions, Bad beat jackpot etc. I've seen the money used to buy cars, feed the players, bu WSOP seats etc. The problem with this now is that the Casinos are stealing this money in a round about way.
The last casino I worked at has got into the entertainment business. They've been holding outdoor concerts, and MMA events. I would be surprised if the Casino gets 200 people who pay for tickets. The casino makes the blackjack pit and poker room buy tickets and give them away to it's players. The problem with this is they charge $150 a person for general admission tickets and up to $500 for VIP ( A folding table close to the action). This should be a fucking crime and it seems as if theirs nothing anyone can do about it.
It's even worse in Blackjack because in Oklahoma they charge a .50 ante per hand bet. This money is the houses take. The State is suppose to get a percentage of the winnings off bets and the rest is suppose to be returned to the players. However the Casinos entertainment company takes it all with overpriced tickets.
