Rude, unwilling to help

They are rude towards woman. Every time I go in they "can't" help me but they help my husband who regulary goes there. they can see on the system that we are regular customers They raise their voice towards me even though the other cashier told him that we usually gets R200 for it. He just pushes my id and my orbital and says sorry no and walk away. They are rude towards me and this is the second time this happens.
