Unprofessional manager Terch

Hi there! I would like to lay a complaint about the Shoprite that's in Cosmo Mall the lady called "Terch" the admin manager was so rude in front of us as customers, she was shouting one of the Cashiers asking her why she is starring at her insulting her in front of us And that was very unprofessional and it was not the first time because I always buy in the store this is the second time I started invistigating people who are working there about this lady 3 people said it's how it is this lady makes environment toxic to everyone and we can't keep on buying in such environment this matter need to be taken very serious because Shoprite will lose customers because of Terch
