Cashiers with attitude

I just bought few items which were supposed to fit in 1 plastic but because i had bread and frozen stuff i was given 2plastics but on my slip 4 plastics were scanned i go back to the cashier to show her that she made a mis(NOLUFEFENKOMBI( she just said (zokunika imali yakho) no sorry no nothing with big attitude, stop treating black customers as if you are doing them favour if it was a white person you would hear them address them as Maa,am. Do not call me this is not about the 2,60 for the plastic but the integrity this is our money you cant be this careless and give attitude when you are tired go home.
