You would think they would have the inexperience issue taken care of ahead of time. Too much inexpierience in all phases of the casino (pit, table, cage) could bleed a place like that dry. It would be a haven for scammers. Maybe if they started with 25% new, and 75% experienced, and phased that back over a year or so, they would be better off.
Or maybe they have accounted for, and accepted some loss up front as being inevitable. Paying the experienced staff from out of town I'm sure commands a pay premium.
