Being told by a cashier that you're boring for not buying a product

The service I got from Mall of Africa staff Rodney Dineo Maribe that guy disrespected me live and told his colleague that I bore him imagine being told right in your face that you're boring for asking him to call the supervisor to do void, in fact most of Checkers Mall of Africa thinks they are doing us a favor by rendering a service, I'm so ****ed that they look at us and disrespect us right in our faces is it fair?
