Well, if you purchase a suite, do you want somebody in your suite? If you purchase a home, do you want somebody in your home?
Here's the difference, Lonn. Seats at a stadium aren't a home. People can't go there when the Stadium is closed. Purchasing those seats allow for people to sit in them for before, during and after home games. It's a "suite" only because you call it that. Nowhere else is in the world are padded plastic seats without a roof considered a "suite". Actual suites are in hotels and on cruise ships and chalets in the Swiss Alps. The New Stadium is an outdoor sporting event venue, not a vacation destination.
And as PeteAbe has brought up, those seats are almost always empty in the hours leading up to games. If fans from other sections were watching BP from down there and a ticket holder politely informed them that they were in their spot, I'm sure they would move out of the way. Apparently the obscene ticket prices at the New Stadium have spared the wealthy the indignity of interacting with us commoners for even the briefest of moments. Which would be fine, but again, those tickets still aren't totally sold. The Yankees are still screwing their real fans in the name of their make-believe dream customers.
