Disgusting service

I am really disgusted on how management at the Super SPAR at The Square, Boksburg treat their customers. Their cashier was rude to me for paying with a R200 note to buy an item which cost just over R20. And learning of tis, I didnt get an apology, instead they told me not to be rude. I stood there in disbelief. SPAR is a joke...a total joke. For those who get proper service at SPAR, you are one of the lucky ones. I don't shop at SPAR, and never going back there again. I am totally disgusted by the treatment there.
