I once worked cooking pizzas, a long time ago.
Those look ok. Pepperonis that are sliced by a slicer with a slightly dull blade, will be depressed by the slicer on the edges. That is what it appears to be, to me.
The guy is sort of a muckraker. To tell the truth.
Just saying. They look ok to me.
And the different sized slices? Clearly not from the same pizza. And if they are/were, did the server drop the pizza and reassemble it? Either way, toss it and make a fresh one.
The pieces of his pizzas cannot be aligned to make a circle.
