Terrible attitude from both cashier and manager

Good Day, We shop at Pick n Pay almost EVERYDAY!!! Since ive moved to Birchliegh which has been many years, We went last Wednesday and did our shopping as usual, we go to a cashier to pay and as she is scanning our items she is throwing them, when I say throw I mean throwing them across to the end where they pack our groceries, I then asked her, why shes throwing my food? I didn't get a response I got a dirty look and then she continued to throw my stuff. My husband then asked the lady that packs the bags if we may have another bag, I then got money out to pay the cashier for the extra bag, and yes you guessed right at that point she literally tossed the bag aside and wouldn't let me pay for it. my husband then flipped and couldn't believe the attitude, just then the manager walked past and my husband said to him unfortunately your cashier has a terrible attitude, ha!!!!! you wouldn't believe what he did!!! he stood there telling this cashier to get up, get up get up!!! she was already assisting the customers behind us who had witnessed her bad attitude, and here the manager stands there telling her to stand up and she laughs at him as if its a joke. he was super mad, I can understand, but to reprimand a staff member right there in front of all the customers and then still ask her to stop helping another customer and to get up, we were so appalled we actually hurried out of there both appalled, hello peter was currently under construction that is why we have only logged this today. I still have the slip with the cashiers name on it, and am super dissapointed at a shop that we shop at all the time, my whole family and all my friends go there. Please be advised that Word of mouth is a way of adverti*****t and I sure will inform everyone I can of the terrible service. I pay for my food and I dont need someone throwing it around. Ill rather drive a few more minutes to Soutpansberg Pick n Pay where we get treated like paying customers. Pathetic service
