Guy is just asking for chicken carbonara with no bacon and the server keeps telling him it isn't possible.
Then this lady gets super incensed and starts going off calling everyone that disagrees with her "medigan" which is apparently a derogatory term used by Italian Americans to insult people they think have "lost touch with their Italian heritage"

Kind of, although there's also a factor of Americans claiming to have a larger role in something they were a minor player in.
Carbonara was "invented" in the 40's, but it's mostly just adding egg to a pre-existing dish called pasta alla gricia which traces back to Papal Rome
Pasta alla gricia is pecorino romano, guanciale and black pepper
Pasta alla carbonara is pecorino romano, guanciale (or bacon), black pepper and egg.
American GIs and their bacon and eggs + Italian cooks already making a dish with pepper, pork and cheese = Carbonara. Cream was added later stateside.
So yeah, while it's true that the word "carbonara" didn't exist in any cookbooks prior to WWII and the dish as we know it wouldn't exist/be well known if it weren't for WWII, it's not something conjured out of thin air
