FFN: The first pizza place that was in the town, the managers never show up, but they keep it open because it still makes them money. A subset of customers have started trying to run it to the "standards" the managers set up but the managers are nowhere to be seen and these "rule enforcers" are harassing people and chasing them away. The place is rickety, termite infested, yet some people still think it has the best special recipe pizzas.
Ao3: The pizza place that was made by people who were tired of FFN Pizza's bullshit. You can order any kind of pizza you want and they'll make it. The managers listen to the clientele and actively maintain the restaurant, although they take awhile to implement suggestions sometimes. It is also reservation only, and you need a club card to eat there although you can get one from a friend who already has one.
Wattpad: The pizza place that just wanted to be trendy and make money. No club cards needed, so teenagers can just walk in and have a slice. But after awhile, the managers started wanting new customers to put their names on a list of customers, and they give out an ID card, and you need to display that ID card to eat there. Now the managers are changing the types of pizzas they offer because advertisers do not like sausage pizzas. So no more sausage! People are trying to get Ao3 Pizza club cards for sausage pizzas now but when they get them they bring Wattpad Pizza attitudes with them.
WebNovel is putting their pizzeria advertisment on AO3's door. People get annoyed by it and refuse to visit
