Poor customer care

I visited the store on 26 September 2015 at approximately 11:45 am and purchased chutney woers from the canteen in a small container the lady dished two pieces of woers so I politely asked her to dish more of the woers before she even moved from the dishing section and she very abruptly responded \I DID PUT WOERS ALREAT SISSY!"and i re**** yes but im asking you to put more and she arrogantly rep**** \""OH OKAY THEN I'LL HAVE TO TAKE OUT THE SOURCE TO MAKE SPACE! (We were conversing in Zulu) and she went ahead and poured out the juice and added 3 woers pieces and gave me the container with a mean face and quickly walked away! Now I dont understand why someone would shout at me for wanting to buy more"
