According to research from the University of Guelph, hotdogs are comparatively uncommon in fast food because hotdogs are harder to cook consistently and have a shorter window of enjoyability which makes them less suited to fast food than hamburgers.
The corporate parent of Carl’s Jr. bought Hardee’s in 1997, but Carl’s stayed pretty much the same.
What really defines fast food is mass production and uniformity.
Interestingly, I always assumed that “fast food” meant the type of food; so a hamburger, even if not made from mass produced ingredients, would always be a “fast food”.
In context, though, the original commenter considered things like street hotdog vendors to be fast food. That is not unlike the kind of delivery you would find in antiquity, even if the actual food product differed.

Technically, what really defines a term is how it is used in a certain context and how it works towards reaching a shared understanding, which was achieved with the original use of fast food found in this thread. You are right that the definition that emerged here does not align with definitions found in other contexts, but those other contexts are irrelevant to this particular context.
> It’s a weird thing - people in the USA know what you mean by fast food and somehow McDonald’s under a heat lamp counts (rarer now but still found) but burgers at the gas station under a heat lamp don’t count.
But, I think it's a bit rich to call it the origin of fast food. Modern fast food in terms of what we think of as technology and business model is a bit broader than that. And just "food you get fast" is obviously far older. The original "fast food" in that sense was getting bread from a baker.
Particularly when we just got finished talking about fast food in antiquity. I suppose that explains why nobody said such a thing.
Curious about this history. According to Wikipedia, fast food was common during antiquity, while the hotdog wasn't invented until the 1400s. White Castle seems to be recognized as the origin of modern day fast food and it opened as a hamburger joint.
