Terrible service in BelaBela FruitnVeg

Went to Fruit N Veg BelaBela and was paying for my purchase when the imbecile at the till called Portia said I should go back weigh the Bananas. I told her the guy is not there to weigh so she give me this tone and says I should leave them. When I tell her it's no longer my responsibility to go back and find the guy to weigh she has the nerve to tell me I'm giving her attitude. Even dared me to go to the manager. What sort of service is that where customers are treated as ****? I called the manager on the phone a who was not even close to bring helpful. **** service.
