Sworn at by a staff member

Around 4:30 Sunday morning my cousin &I went to Lambton KFC drive thru &were served by Nokuthula who told us our order will take 20 minutes.We waited inside &saw cars after us being served.My cousin asked Lebo B at the tills why we hadnt been served who looked her in the face &walked past.When Nokuthula walked in my cousin asked her &she said the other customers ordered something else.My cousin told Nokuthula about Lebo B &demanded to speak to a manager.When Phillimon arrived we explained to him what happened &reported Lebo B.She said she was not about to answer to \amasimba\",meaning ****.When I repeated her statement she just looked at me &my cousin asked her if she called her question ****, to which she responded \"yes\".My cousin got upset &told her \"**** you\" &Lebo B responded \"**** you too\" pointing a cooldrink buddy at my cousin. When Phillimon asked her to apologise she said she will not apologise to \"amasimba\".I asked Phillimon how he can allow his staff member to disrespect a customer &him like that he said what else must he do, he feels he did his best.I demand that this woman be relieved of her position at KFC &a new manager be appointed,the current one is useless."
