That's one notorious casino for getting chips regardless of your tactics. Well, my secret was that they use the $1 chip on the roulette table. I just bought in for $25 and when things got real busy, just said I would cash them at the cage. It's extremely hard to get snappers since the only way is to win them. When you get two, they want to color up to a $5 chip. Take a restroom break, pocket the snapper, and continue playing. Just buy extra snappers from the players on either side. I usually give three $1 chips for a snapper. Players are happy, dealers are happy and chippers are happy. Getting them is part of the experience.
