So writing to the manufacturer of the pizza with a bolt.

Here's what we have so far:

To whom it may concern, I am writing to inform you that I recently bought a pizza manufactured by your company at Leos Fine Food and Wine in Kew, 3101 on 22/07/24 which contained a 1.5cm x 5mm metal bolt (pictured in the attached). It need not be explained the risks of finding a foreign object like a metal bolt in food.
It is my hope that you bolster the servicing and upkeep of the equipment in use to ensure this doesn’t happen again to other customers. Kind regards.

In plain language... that shit is gonna send peeps to the dentist buy a screwdriver and a torch.
