What other fees can the casinos and hotels can implement?

It is very simple. They can do what the Indian casinos in California used to do. They can charge rent on blackjack bets whereby you had to put a rent fee down before every blackjack bet. The rent fee was based upon what you were going to bet.

I heard the calculated disadvantage to the player was 17+%.

I am sure that the bean counting corporate a-holes read the Advisor. Be careful what you ask for, even in jest. Those bastards could implement some of your ideas since the general public is too stupid and ignorant to see how asinine these money gouging fees really are....

Most Chinese restaurants now days charge about $1.50 per serving of rice when it used to be free before. Also the house tea pot used to be free but it is common now for them to charge about $3 for a pot of tea.
