Angry annoyed customer

I went to BOXER TRADE ROUTE MALL LENASIA this morning 23rd Aug 2021. Took 12 loaves of white bread. When I got to the till point the cashier started mocking me to her college. Then she asked if I'm going to eat all this bread. After that she went on to say 'COME ON LOOK IN YOUR POCKET FOR R5. My husband gave her R110 and our purchase was R104.98. She laughed loud at us and kept on mocking us. ALL I WANTED TO DO WAS PURCHASE A FEW ITEMS IN A PEACEFULL MANNER. This is so disrespectful to a customer who support the Boxer group on a daily basis. Please do something aboiut the attitude of your cashier. Your cashier needs to be sent on a course to learn people skills. She is arrogant and ill mannered. She needs to take some lessons from the people at the bakery section, who is so kind and ever - willing to help. Please do something about her as we cannot take this attitude towards customers so early in the morning. I got her name as well
