Cashier had a bad attitude

On15/12/2017 at 11:39 i was in pep store at Merriman street, Vereeniging to purchase some good , i am a regular customer at this store and while shopping i decided to make a lay-buy of two dresses. When i reach the till point i was helped by cashier: Puleng and she told that i need an identity document if i want to lay-buy , i told her that i do not have my id with me however i had the driver's license and im a regular at the store my details are already on the system, she didn't want to assist she had a bad attitude towards me and she was very arrogant and she said "what is it that you want me to do ? I need to scan your ID" . i have previously made a lay-buy without a id on had without any problems. I felt disrespected by the cashier and she lacked passion on her duties she kept on complaining in the presence of customers that the other cashier is passing all the customers to her , the is only one speed point. functioning at this store thus making the service very slow.
