I recently did a floor evaluation for a small casino where I went over the PAR percentages for every game on the floor with management. Some people are completely clueless.
I know quite a few casino Slot Directors and am amazed at some of them. I still hear them discussing their concerns because a machine has been "hot" or "cold" lately. Also, the machines that are "due" to hit because they had so much play recently and it is going to ruin their weekly numbers.
ShuffleMaster should market another shuffler, which is the exact same shuffler, as the pre-shuffler. It'll sell, "Instead of washing, you put your cards into the pre-shuffler!"
