Start adding in non-English speakers, attention deficiters, and yes even
far-sightednessers. You are starting to talk about a major chunk
of the big mac buying public.
Illiteracy has many definitions, not just the complete inability
to read and write. There are many degrees of illiteracy. Having
little or no formal education, inferiority to an expected standard
of familiarity with language and literature, violating prescribed
standards of speech, can all be interpreted to apply here.
As to your most relevant question, what percentage of adults is
unable to read a meal order from a large illuminated display?
I don't know and the best approach is to just do it. Those who
can't read will be too ashamed and take what they can get, what
they server thinks they ordered. Perhaps another relevant statistic
is what percentage of people knowing what they ordered and had
confirmed it on the large illuminated screen, actually turn back
and complain to get their order right? I would guess it's less
than 1 in 5. That's the paradox of fast food.
