The fact that the Cardinals are the only team that does this is a black eye, my guy. Just admit it sucks to look cheap. A billionaire nickel and diming millionaires.
You could probably find a bunch of things that every team does uniquely if you look hard enough. I'm not necessarily convinced the Cards are the only team either. They were just the only team where a player mentioned it on the report.
Either way it's trivial. But it's a good thing for people to latch onto.
Far, far more important was that players said the food wasn't great.
