One concern I have is the increased marketing (taxi) costs in LV. Once it starts escalating, I hope it does not get out of hand in trying to compete with other clubs. I think that these costs can more than wipe-out any increase in sales.
There is a signed agreement (3 or 4 major clubs) and they send people around to check each others clubs to keep things honest! There is also a substantial penalty to any party found to have breached the deal.
