Pep Store cashier attitude

The is cashier her name is Cece from Thembisa Plaza she had a nasty attitude towards me while I needed a service regarding Paxi, when I requested to see the supervisor she said she is not off. The security said the Supervisor is here so if you don't mind waiting for her you can which I did. Then they spoke aside the supervisor came to me with attitude saying I must not disrespect her staff, which is something I never did.
