What to do about list cutters

[TakenItEasy]

At the casino I play at there is often only 1 table at the game I play and the list can get extremely long especially on the weekends.

You can call ahead to get on the list so that's not too big a deal with planning but many regulars have an "understanding" with the floor and just take the first available seat. This has created a huge problem of cutting out the new players (fish) who give up on waiting. The game used to be extremely lucrative but it has gotten to the point where you rarely see a new face outside of the 15 or so regulars even though you often see 50 names on the weekends. I also believe the staff sometimes deliberately keeps it down to 1 table just to keep the tips comming.

Is this a common problem at other casinos?

The top dogs don't seem to be in on it since I saw one kick a player off the table before and threatened suspension to the floorman but they are rarely around. I don't want to be the narc so any ideas on the best course of action?
