Judgmental attitude

went to Mr.price in Carletonville with my 2 daughters when I reached the counter, I greeted the lady, she greeted me back and then looked at us (we all have dreadlocks), then she calls "abo jahman" which is a term used to describe people of a Rastafarian religion, I asked her if she knows what a "jahman" is and she rep**** with attitude "yes it's a Rastafarian" I then asked her if she knows that it's a religion of which myself and my kids are not followers of and don't appreciate being called that and she rep**** "oh whatever" and rolled her eyes. I really feel she was insulting and degrading me and my daughters because we are not rastars, we don't use ****. I really don't like the way that she classified us.
