Rude and disrespectful

Thabiso was very rude and got very impatient with me as she was taking my order which as a result she messed up my order. When i asked to speak to the manager, Sherine came and said she was the manager. She called Thabiso and as i was explaining what the problem was, Thabiso walked away and said she had better things to do. Sherine \The Manager"then said \""She ( Thabiso) has attitude problems which she cannot fix and therefore i must just take it up further\"". People like her should not be working with customers because clearly she does not have the heart and patience. I would gladly appreciate it if such incidents can be prevented from happening."""
