Unsatisfied customer

I bought a box meal of burger chicken and chips at KFC Maponyamall on 25November 2021. The burger did not have cucumber and there was no tomato. The chicken was undercooked. I was not given salt. When I asked for it I was told that it was finished. I always clean the table and throw away into the bin and I dont mind doing that. I was shocked when the lady working there asked us to please make sure we throw away the containers when we are done. I didn't see her come up and clean yhe tables while we were there as busy as it was. Fortunately customers threw away containers inside tue bin.
