All that money comes from the fans. It is unbelievable what the concessions bring in. Last I checked (20 years ago) two 7 oz beers and two hot dogs was over $30. I don't care for sports either, but wife wanted to take her dad to a ball game for his birthday, and insisted on the beer and hot dog. I didn't want either one, tbh.
If you get to thinking you’re a person of some influence, try ordering somebody else’s dog around.
