Burger King review: foreign objects in middle of whopper

My daughter and I took lunchbreak today at noon, we decided to go to our local burger king in Faribault, MN. She ordered bacon whopper combo . As we got back to our place of employment we began to eat .. halfway threw her whopper she bit into a hard object, a ROCK! I called our local BK and the manager was like .. ah ya I am the manager, as I told him he seemed very confused, and said the meat must have been sent that way to them because they don't drop their meat ... he asked for my name and number, and hung up on me! I then tried to call back to only be hung up on once again. I am disgusted, pissed, and hoping my daughter don't need see DR. as she is also not feeling well. I don't want their coupons this is not my point behind my complaint .. its to let people know, and to check their food before they serve it, I am also going to contact the health department because this is awful, and whats worse the management DONT CARE !
