If you take care of the dealers in the casino, sometimes thay buy you drinks. A few years ago, we were on a Ncl boat and the pit manager would stop the game and have the waitress get us drinks on them. we probably tipped more than we would have spent on the drinks, but we looked pretty cool when everybody else was signing their name and we didnt have to. A couple a carnival dealers took care of us but dont remember how much. No matter where you gamble- ALWAYS TIP YOUR DEALERS.
