I'm going to kick a special needs child out of my restaurant
I need to know more about the context of you wanting to kick a special needs child out of your restaurant.
I hate children. I've had bad experiences when they were in my restaurant
People are generally expected to be kind to children, especially in a service setting, and it is wrong (and possibly even illegal) to refuse service to someone who has a disability.  It's fine if you want to have a restaurant that only caters to adults, but you need to be open and honest about this, right from the start.  You can't allow some children but exclude others.
I'll kick him out when I see him. Bad people make good people look bad.
You can't really refuse a special needs child service without looking like a terrible person, and I know that you don't care but this sort of publicity could hurt your business. Who will want to go to the place that kicks out special needs children?
