I'm getting from the story that her grades started dropping after she started working at Hooter's. Sounds like to me she's on a downhill slide. I bet if she was in a job where she was using her brain instead of her body, her grades wouldn't be slipping.
FWIW, I agree with you, Hooter's isn't a place for small children and I have no problem with adults patronizing the place. If you'll read through the posts to me, you'll see that some people feel I'm sheltering my children by not taking them there.
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.
