When I go to Europe or Asia, I have high confidence I can walk into a random restaurant/cafe and get good food made with high quality fresh ingredients on sight. Of course not every restaurant/cafe is good, but enough are.
Europe. I've tried such american restaurants like CCF, and they're not just "reheated factory produced food". Even Olive Garden isn't that (the prepare stuff on-site, contrary to myth). In fact, they're better than many local ones.
I'd say it's less about liking good food than liking to signal class status. The same people have no issue eating shoddily made chinese take-away or in-and-out or total prepackaged factory crap sold in their upclass super market, because those are not associated with a class stigma.
You see the most obsession with class concerns in areas where you have people who are class mobile: There's a lot of nouveau riche and upper-middle class people in tech, because tech has been a massive boom industry. Likewise you see a fair amount of class concern among people falling down the social ladder, such as the generations that grew up within environment of an old-money fortune, but for whatever reason that money was lost.
I feel like everyone is talking in circles just wanting to be right on the internet.
In Australia at least where there are some chains for casual/fast food but not so much for restaurants, I haven't sensed this stigma because that dining niche is occupied by the local hotel's restaurant or a pub with low to no pretenses but a decent to quite good meal.
I'm not sure it's that, since 99% of the consumption of those same snobs are heavily corporatised consumerism. It's just the expensive kind marketed to more affluent suckers. They're for example OK with Starbucks, the kind of "heavily corporatised consumerism", and all kind of BS upscale consumerist brands like Lululemon.
Nobody gives a fuck if you go and eat in a "middling" establishment equivalent to CCF in these here parts, even if you're old money. And nobody cares of most other US shibboleths of class.
Whereas in the US it's as if something like CCF or, god forbid, Olive Garden, has leprosy, for some types of "high class" or wanabee so, people.
