Stinky customer service

Was at Cambridge food Tembisa 30 Min ago, had to wait for a price change on an item. The cashier caller Kristel, whom I guess is a supervisor. As I was waiting coincedentally our eyes meet. Then she shouted at the cashier " I called him,what else do you want me do do? Should I jump on him? I mean really, was there a need for such a statement? Please who ever is supervising Cambridge, respect between employees is very important. When I complained about the way she spoke to the cashier she told me who do I think I am. Her attitude stinks, I really don't understand what the hell she is doing there if she thinks she is better. I hate people who undermine other people, especially employees infont or customers. Nxa, I was so ****ed off!!
