Most of these dugout seats come with access to a premium club area with a full bar and amazing food spread. I’d assume the people sitting in these home plate seats were at the game but chose to hang out inside and stuff their faces, get drunk, and try to pick up younger women like any obnoxious, Wall St. Yankee fan would.
I read something today that the brand new LA Clippers basketball arena has no TV’s in the concourse and all the TV’s inside the private suites are disabled during the game to ensure people are in their seats watching the action.
