Tonight we went to Mcdonald's and when I bit into my double cheeseburger I found that there was a small sharp hard bone in it. I was able to pull the little bone out of my mouth and still have it... as well as the rest of my sandwich. Im wondering if there is anything I can do about this as I am very upset and my tooth still hurts. I don't think there was any physical damage to my tooth... it just hurts. But like I said I am pretty upset and disgusted. Can I sue them for this?
