Well, given that the GFFA has at least a million populated worlds, and that these worlds have been growing ever-closer for the past 25,000 years, odds are pretty good that at least one world in all that time developed the concept of the fifties diner. I mean, we did, and it only took 10,000 years (from the beginning of human civilization) and 2.5 billion people (world population in 1950). It was still pretty stupid and did nothing to invest the film with awe or wonder, but it's possible.
