I hear what you’re saying, but think of it this way too; getting to watch a practice round is a lot more personal than a public game. During a public game, the player has to be in full focus mode and has to basically ignore the crowd for the most part. In a practice game, they get to actually be on the field one-on-one with the player and converse with them. Think of it like going to a soundcheck of your favourite band. It’s only you and a couple of other people in the audience listening to your favourite songs without thousands of other people singing along as well.
