My first observation is that a casino should never "86" a player unless that player is a cheat or engages in disruptive behavior. I might even go so far as to support a commission regulation to that effect as it applies to machine players. If the casino is offering a promotion that hurts them, they need to revamp the promotion.
So why does a casino offer a promotion, be it a car giveaway, or free gifts or any other type of promotion which draws in players which would place advantage players in a position where they can make substantial money. It obviously is not to provide a living to A.P.s, but to help the casino's bottom line. To do that apparently they need to attract smaller players whose play is not enough, as a group, to be unprofitable to the casino. They need to limit the potential win on a promotion so that any individual player, or team of players, does not have the capability to skew the overall benefit against the casino. The simplest way to do that would seem to be to limit the amount that any one person can benefit from any one promotion. That could be the often used limit of a maximum number of $s in on a promotion or a limit on the number of entries per player. That is easy to do in this world of computer tracked play. It is more difficult when it comes to identifying people who are playing as a team. I would not allow a player to hand off a machine to another player when the promotion would be worth it to organize a team to play it. Team play on a promotion is more problematic for casino management than the individual big player.
Slot directors thinking seems to be similar to Wall Street CEOs where the important thing is to show a good profit in the next quarter to increase their bonus or pay, and not necessarily to do what would be in the long term interest of the company. I think this is primarily the result of having casinos run by public corporations rather than people who have an interest in providing services (for a profit of course) with gambling backgrounds. And it especially applies to those places which might be looking for a buyer in the near future, whether individually owned or corporate owned.
