Sasol Umgeni, dumb cashiers

I've been a customer of this service station for a while now, and while the petrol attendants are courteous and efficient, the cashiers inside are absolutely useless.

On many occasions after bringing my items to the till point to pay, I was outright ignored by the 2 cashiers, who continued to have a conversation in isiZulu. No greetings, no thanks, scanning and tossing aside of my items, no courtesy at all. I hope this will be addressed by management, or I will do this personally.
