Mcdonalds / fly in drink & hard thing in burger

My sister and I ordered a double cheeseburger, a mcchicken, and two small fries. We only recieved ONE fry. The mcChicken's bread was hard, and the meat was a little cold, and just... obviously not fresh! She couldn't finish her burger because she bit down into something hard. She pulled it out of her mouth and it was a small, white, hard IDK WHAT. She says it resembled a tooth, but it WAS NOT hers.. IDK WTF it was! I will not be eating there ever again.. I am rarely happy with the food. This was the last straw.

Also, my bf went to a mcdonalds and there was a FLY in his sweet tea! NO LIEEEEEEE !!! EW
