Rude cashier

Mpumie the cashier who calls out orders is incredibly rude to customers. She blatantly told us she doesn't care if we've been waiting for 30 mins, we'll wait till she calls our orders. She's rude and doesn't know how to speak to people. We understand the store being busy but the way she was going on about it really ****ed me off. She needs to do better, we are paying customers!
