744.Paragraph 30 provides that a service provider does not breach the requirement in section 29 not to discriminate in the provision of a service if he or she supplies the service in such a way that it is commonly only used by people with a particular protected characteristic (for example, women or people of Afro-Caribbean descent) and he or she continues to provide that service in that way. If it is impracticable to provide the service to someone who does not share that particular characteristic, a service provider can refuse to provide the service to that person.
