Gratuities are added on the services at 20%. I once saw a man ask for a bottle of water at casino bar he didn't have a package. Waiter handed him the water charged his card plus 20%. Just for picking up bottle of water in front of his eyes. Oh well, rules are rules. I remember one of the times I did get beverage package I was at casino bar and wanted a glass of villa maria SB. He said we normally don't stock that here and offered me one from classic package. Nope. Paid for premium. Well he found a bottle for me.
