Every single video he's bitched about the vinegar based sauces.
His outspoken aversion to vinegar-based BBQ sauce is bizarre. Especially considering the love affair he had with Balsamico a while back. Like a lot of Jacklogic, it's self-contradicting and makes no sense. It's predictable that he gravitates towards sugary sauces in any case.
One thing that this does suggest is that our theories regarding him having a diminished sense of taste for some reason (in response to his constant overseasoning with shit like cumin) are probably inaccurate. He's tasteless by choice, not by nature.
This is why I would love to see Jack travel abroad. Even continental Europe would be full of restaurant owners and waitstaff (Who aren't reliant on tips in many countries there) who would figuratively or literally throw his ass out.
That would be gold. It would be like when fellow fat cow Patrick S. Tomlinson, Esq. went to a Parisian café and ordered scrambled eggs, and the staff told him to order something from the menu or to get lost.
Dining etiquete is very different on the other side of the Atlantic. The 'costumer is always right' shit does not fly here. Complaining about a dish and expecting a new one to be made free of charge will get you thrown the fuck out of most places. A lot of small American establishments seem to have this mindset like they're gonna become a franchise in the future, so they bend over backwards with their balls in a knot to appease boors like Jack. The average establishment owner and server in a Europoor place behaves like a regular ass dude, and will
not respond well to rude and entitled patrons, especially not American tourists who they have no incentive to treat with kid gloves if they misbehave.
Northern European diners will be incredibly annoyed by the Scalfanis' obnoxious chatter and filming of everyone and everything and give them death glares. In Southern Europe it's way more socially acceptable to be loud and gregarious in a restaurant, but that doesn't mean they tolerate self-important cunts. Jack would probably be absolutely miserable at an actual Italian restaurant because the pizze aren't gargantuan undercooked monstrosities laden with toppings, the portion sizes aren't humongous, garlic bread isn't a thing; and to top it all off, the uproarious din of the Italian patrons enjoying themselves would drown out his insipid JOTG commentary.
