In many Sin City casinos and elsewhere around the world, gamblers at tables and slot machines are served free booze, snacks and other goodies. Of course, it isn’t that the casino bosses are kindhearted. They figure the more plastered you get, the less you’ll be able to make sensible bets.

So, when you see servers wandering in your area, ask for the free drinks and other items they’re handing out. Figure that if you take advantage of the offers five or six times a day, you can save $50 or more. Be sure to tip a buck per drink.
