I want to write a dystopia and find it hard to convey that things aren't at all right. I had planned to convey this in subtle reading clues, but I am worried that certain types of readers - or perhaps most readers - won't get it.
In my writing circles there are readers who admit they are completely oblivious to body language, social cues, and other subtle things in real life as well as reading on paper. When I speed-read, I am also equally oblivious, so I imagine the circle of people who are oblivious to subtle writing clues is quite large.
In other words, I would want to write something like
"John Smith stuck his credit card into the machine, waited, and walked away."
But I fear that my readers won't get it. (This is a strange thing to do - John didn't get his card or anything else back, seemed to serve no purpose but to waste time.) I realize that this is a poor example, but I'm trying to have my example convey that something here is not at all right.
The crux of my question is that I am worried people will miss subtle clues that explains what is going on. As an author, should I be giving the clues and then expound so the reader gets it? If I decide not to, am I a terrible person for disregarding readers who may have a disability/disadvantage/clinical issue - or should I write differently to make my work accessible to them? I also wonder if I should be catering to as many "reader types" as possible so my work will be read and enjoyed as much as possible?
(Bonus: and did you notice what is wrong in the picture? I put it there to try to demonstrate subtleness and how we sometimes don't notice).
