If you had the slightest idea how many rats infect the kitchen of any restaurant or how the food preparers prepare the food behind the kitchen doors in any restaurant, you’d never eat in a restaurant again.
The only difference with a pizza store is that unlike other restaurants they make the food in front of you. And you see how bad it is. In the fancier restaurants where they don’t dare let you in the kitchen or see the shmutz near the food, it is so much worse.
