Choked on rubber

<p>I bought a McFlurry this evening. Began eating it and swallowed my first s****ful. All of a sudden I feel a hard bump in my throat and start chocking. After frantically trying to cough it up, I eventually did. A piece of black rubber!</p> <p>After I calmed down, 20 mins later, I began eating it again. Again, I feel a black piece of rubber in my mouth, luckily I did not swallow it this time. </p> <p> </p> <p>I have photos to prove this. This is totally unacceptable! </p>
