Rude assistant manager bullying a granny

Had the worst experience with Checkers assistant manager Nthabiseng who was rude, arrogant and instead of apologizing to me as a 70 year old and crediting me for the mess up they did about pricing she had the audacity to tell me I can take it further if I want. She made me wait with my bad knee while she continued to assist a white customer not giving my matter any thought. I'm really disappointed with the hygiene and Custer service given by the so cold assistant manager. Will make sure all my senior friends and they family's know of Checkers olivedale corner, sies
