Burger with extra dirt as seasoning

Deserves NO star just so we're clear. I ordered a chicken crunch burger for delivery, took a bite and thought it tasted strange, opened it and inside the chicken patty and the bun was full of black and brown grit and grime. I'm absolutely disgusted that I was served this, it was clearly dropped on the floor, put together and packaged and sent out for delivery. This is horryfing especially in light of the pandemic! Will never ever trust Burger King N1 City's food again, ever ?
