If these were run of the mill tickets it'd be one thing, but there is a different expectation (albeit an unwritten expectation) with legacy seats. These are the programs top donors... and their seats are being filled with the opponent's fans?

This isn't just about red vs blue, Mormon vs Jack, sober vs belligerent, saints vs convicts, but rather a significant program donor that has a significant financial interest in the program. I get his dilemma and I don't see any issue with his request to them.
