In the private business context, service can be refused to any person for any reason so long as the refusal is not based upon a discriminatory purpose protected under the United State's Constitution. Such protected matters that one cannot be discriminated against in the private business context would be race, creed, ethnicity, sexual orientation and gender.If you were refused service at the private business establishment because of your alleged poor reputation, the refusal seemingly was allowable and you legally would have no legal recourse for such refusal.
