Rude cashier used foul language

Whent to the Lanseria Spar and came across the most rude cashier in my entire life, her name is Zomo or something similar to that. She shouted at me for telling her to scan all my items, she refused to void what I taut was a error, her reaction to me telling her to void if theres a mistake was " I dnt void, I'm here to wrk, voiding is for ppl who don't work" " how must she know whats mine & not mine" when I clearly separated my items from the lady tht was shopping with me. She swore at us while cashing up as well. I have never seen such a rude person ever, hope she goes for some training to change those bad manners!!! Totally disgusting for a retail chain store.
