She's a freshman. She doesn't have enough history there to know if she's sliding or not. College jobs are college jobs... and waitressing isn't unusual as a college job. Really tuffy, the only thing possibly objectionable about Hooters is the name. If not for the name, you'd have a hard time seeing any difference between Hooters and any fern bar.
If she was making good enough grades to be admitted into college and onto the cheerleading squad and now she's failing classes, to me that's slipping. We are far enough into the school year to make that determination.
Maybe that's why she's yelling discrimination, it's the only way she can win her place on the cheerleading squad since she can't make on her grades.
