First off, I would like to say that this is a good piece for a flash fiction type of writing. It was just a normal day at the amusement park, and so the reader is put on a sort of relaxed aura, which I missed in reading stories. All of the stories tend to try to catch the reader's attention by immediately placing the characters in a tense situation, and this could be sort of tiring, if you catch my drift. I do have a few minor problems with it.
One is about the spacing. You could put an empty line in between paragraphs so reading would be a bit easier. The layout as it is now looks daunting, and the wall of text appears just like that - a wall of text. Usually, I don't have much problems with that since this is a story, after all, but this kind of layout puts strain on the eyes, or at least my eyes. If I'm the only one with this problem, then please do ignore me. 
Another nit I saw was this one here:
Vick smiled.
“Actually, I thought sugar puke would taste a lot better than hot dog flavored.”
Then the roller coaster started and Benry’s voice was drowned out by the clinking tracks as he said,
“Soon.”
Notice the two? I think it would be better if the conversation line and the narration line were in one paragraph, like so:
Vick smiled, then said, “Actually, I thought sugar puke would taste a lot better than hot dog flavored.”
Then the roller coaster started and Benry’s voice was drowned out by the clinking tracks as he said, “Soon.”
They look more fluid and easy-flowing this way, I think.
Also, the intro needs a little more description. What's happening in the amusement park? What's happening around the band as they joked and laughed at one another? Ambient noise? Weather? Things like that should put some sort of vibe to your intro, and it would feel as if the reader is actually "seeing" the event occur, not just merely "listening" as the story is narrated.
As for your question, then this intro could be able to catch the attention of the reader. It made me wonder, "What will happen next? What's the role of the girl? What's the role of the school the girl mentioned?" On the downside, this intro looked a bit bland, so the curiosities I mentioned may lose their edge. I think describing the background a bit will put some color to the story and that ought to solve this slight issue.
