If you look back in some of the old CL threads I think one or two of them, back when non-Platinum/cents could buy a day pass for $50 may have had a revenue sharing component to the lease. Like Amex would pay 5-10% or something of actual revenue collected. But don't quote me on that as its going a few years back in my memory bank and I don't really feel like spending the hour it would probably take to try to unearth said documents.
