They wouldn't dare do that in Soviet Republic of California. They'd have been sued out of business the day they hung the sign. Here, your "visible employees" must include everyone EXCEPT able-bodied good-looking people. If you want the ACLU out of your face, your receptionist needs to be a Black, Gay or Lesbian Jewish disabled veteran from a broken home, who arrived as in illegal immigrant, has AIDS, diabetes, is losing hair, is blind, deaf, and in a wheelchair, and has a colostomy bag, and cannot speak English. That way, you're safe.
