ok, so i have not read any of the other responses, but i guarantee nobody has said this yet, and im positive this is the best tip in this entire thread. the whole point of the casino is entertainment right? dont go in there thinking you will actually make money, its not gonna happen.
sit at the slots. take out money and start playing, leisurely. when cocktail waitress comes around to get you whatever you are drinking for the evening, tip her twenty dollars and flirt with her. if you do it right, and continue to tip decent after that, you will have those 6 oz cups STACKED up on your machine. play the slots chill all night, enjoy blowing 200 dollars. if you win, take your money out, but if you lose, you had fun and got drunk right? cause you prolly would have blown a stack if you went to the bar anyways.
i know im wise.
