China Star | Chinese Restaurant

We having been coming here for years. Never had any issues until last 6 months we have found a silver object in one of our meals. The last one was a couple of weeks ago. We had leftover fried shimp and again it was inside a fried shrimp. We saved it and took back a couple days later. It looks like a piece of scouring pad. It would have coked someone. We gave it to the male cook. He scrooged his shoulders and threw it in the garbage can. My boyfriend said "man this could have coked my grandson" no comment or no I'm sorry or nothing. My boyfriend said you owe us a. Free plate or take it off are bill. He did neither. We kept saying to him at the counter he should reimburse us. He started talking in their language to the lady in the back kitchen. We will not return!!!
