So in sc we don’t have to wear a mask unless the business owner of that store requires it

So, I got my mask on, minding my own business and this man stops me just to tell me that wearing a mask is pointless and that he lived through the virus so, he knows it won’t it kill me. 🤦‍♀️ I was like well I just don’t like getting sick in general, so if you don’t mind I really should be on my way. 🙄 And then I hear him mumble something and I’m pretty sure he said ya dumb bitch!!
