Staff telling customer to get an ********

On 26 August i went into the Checkers in Sea Point. I was standing by the isle buying a pregnancy test. An elder coloured lady working there walked past and this was her disgusting remark: " Ooh, pregnancy test. Get an ********." Like ***, how does one tell a human that and take the joy away from child baring. I have never in my life came across such disturbing behaviour. Bare in mind, dont know this woman. I was upset and told her that i am a customer and she has no right to talk to me or anyone like that. She said she mistook me for her friend. Even if that was the case, how ****ing disrespectful can you be to make a remark like that and laugh about it. And yes,l am pregnant so to make a fvcked up comment like that really doesnt sit well with me. I will be taking this to social media as well as the newspaper if this issue is not dealt with in the proper manner. This is the image of Checkers that she conveys to customers.
