<human>: Condense the text into a few key points

My sister started playing Volleyball at a very young age and spent all of her free time practicing. It was no surprise to our family that she excelled, and was featured constantly in the local news throughout school. When she got to high school her Varsity coach (we will just call him 'Coach') had 2 daughters on the Varsity team, (who were sophomores) and played them more than anyone one else despite the problems they constantly caused with other players on the team. Well, near the end of my sisters last season playing in high school a scout from our University came to watch her play. She got a heads up about the scout coming to watch her and the coach benched her for 90% of the game. We had all of our family come to watch this game, even some driving 4+ hours to make it. Near the end of the game my dad approached the coach, and said 

"You know a talent scout came to this game to watch my daughter play right?" 

Coach says "Yeah, why do you ask?"

Dad-"Because you benched your top scorer for almost the whole game and played your daughters who are sophomores."

Coach-"Why don't you let me run my team and mind your own F*ckin business?"

Dad-"You know, I need to tell you that a lot of the parents feel you play your daughters WAY more than you play any of the other players, they call your team the "Mr. Jones" show.

Coach-"Yeah, well it's a pretty fucking good show isn't it?"

I have no idea how my dad kept his cool. He generally has a very short temper and if that were me in his shoes it would have taken every ounce of energy to not get physical. The scout ended up not offering my sister a spot. (or whatever scouts do when they recruit people) She tried to not make it a big deal, but it was obvious it really broke her spirit. She was damn good and could have easily played University, and she then dropped sports altogether. It was really depressing to see, especially for me as I have never been good at sports.
<bot>: jackass coach knows scout(s) are coming to watch my sister play, benches her for whole game to play his daughters who are sophomores, tells my dad to basically fuck off when confronted. He still coaches.
