Checkers Gezina Cashier.

I have a complaint against a cashier at Checkers Gezina by the name of Desiree, who I believe needs training on customer service as she is rude and arrogant, she always has this attitude that is rude, saying" next please" when I not even done at the till and going as far as calling me parasite. Can she please be given training and knowledge on what any customer is to a business .
