Help me understand what i saw in Nandos eshowe disturbed me when a guy chopped a chicked while in the fire even when i asked why is he doing that because its under which small cuts from it may stick to the meat but he ignored me even when two ladies asked him he kept quite and continued with what he was doing even after they said the customer is not happy whithbwhat you doing which is not allowed. The two ledies when to fetch the board which I believe was cleaned and the guy never bothered to use it
