Bad service

We to chicken Licken Ormonde the cashier was just rude her name is noma. Bought wings on my wing I noticed a green thing I decided to call a person worker there to show her she then advised me to go to the tills and show them I then told her to call her manager. The manager came and told me that the green thing is from a cloth they use the cloth is sanitized so I can it wing..... I have never had such I will never go to this chicken Licken ever again
