Circle K complaint: racist

the middle age gentle man working at the 32nd st and cactus location today 542021 at 9:00pm this happened. I walk in man is not wearing mask.dont really care but literally i walk up to him and until i put my items down and speak to him he doesnt even acknowledge me or put the mask on till i ask for cigs as well. the man is grumpy unresponsive and slow. i walk out and as i do i admit i got mad and told him he is terrible at his job and if he doesnt want to work with customers i suggest he find a job that works for him. he proceeds to follow me out and we begin a verbal arguement. he was ready to fight me. and to be honest a verbal argument between two people is whatever. ok its over walk off. but this man screamed outside while other customers where around and your cameras were filming. saying get the fuck out of here you WHITE piece of shit your cameras recorded this and i just want that racist garbage not working in the front where others have to hear it. i get that employee deals with shit and i wasnt in the best mood either. but its his job to have calmness and not spout racist terms at people. we both were over the top ready to fight but i wasnt racist thats the difference.
