pathetic and unfriendly service at the cashiers

Pick n Pay Waverley branch in Pretoria service is pathetic A negative interaction with a service employee at the cashiers where they always displaying inappropriate behavior, bad manners, and an unfriendly attitude I have never find pleasure to go to that pick n pay. We as customers are the heart of their business and I don't think they are trained to be there as cashiers, they don't even greet you, they only thing that they know is to ask you if you would like a plastic bag? They should be taught how to handle customers that brings the money to the business with respect and also learn to greet customers, not to just grab their groceries like as if we are taking them for free. The service at the cashiers its pathetic and disappointing.
