Hungry Jack's Australia

I purchased a grilled tropical burger from the bigger waters store at 9:22 pm 11/01/2020 through the drive through.

As I have almost finished the burger I have noticed something hard in my mouth and to my ABSOLUTE DISGUST I pulled this piece of plastic out of my mouth.

Please see the photo I have included.

What are you going to do to fix this problem?

I could of chocked on this item.

If nothing is done I will be seeking legal advice.
