Cashier been treated bad by management

I have been to the park square spar on many occasions and I have noticed that the cashier where been treated very bad by management...I'm going to take this up with spar head office because those cashiers work very hard and however that short lady is not sure off her name but I always see her walking around the shop ... She is extremely rude talk anyhow to the cashier in front of everyone.... I'm a regular customer there and if I come there a see that lady do that again I am going to take a video and post it
