Bad Cashier attitude

I am a regular customer at Pick and Pay Panorama Western Cape, and the first couple of times I was overseeing it, but the attitudes of cashiers is getting to much for me now. It cost nothing first of all just to say hello, I always make a point to greed them in a nice friendly way, but then usually the first words coming out of their mouths is.....You need plastic.....seriously, tonight was the same old story, No greeting and infact sitting with her back to the till talking to the one at the kiosk area. Definitely No supervision and forsure No proper training.
