one of the many downsides to owning a truck with a large fuel tank is that you get to stand at the pump for a long time as it fills. boredom sets in, so my eyes wander. i think every pump i use (generally mom and pop stores) has a sticker on the pump saying that it contains 10% ethanol. the sticker isn't large - about the size of a belt buckle (normal belt buckle, not texas sized), so it could be missed.
in my experience, people don't bother putting a small sticker on a pump out of the goodness of their heart - i would guess that it has to be displayed by law, or else it wouldn't be there. if it's not there, i would guess that it's not law where you live. i wouldn't go waving the conspiracy theory gauntlet yet. i doubt that anyone is not displaying it in order to hide what it is.
a very tiny percentage of the population knows anything more than "gas goes in my car". if they introduce another (not a replacement for e-10) fuel then in a few years you can expect a new nozzle size, and vehicles will have fill pipes limiting what will go in them. if you are old enough to remember the days when "regular" meant leaded fuel, not non-premium unleaded, then you will remember that vehicles requiring unleaded went to a restrictor in the fill pipe so people couldn't put the wrong fuel in by accident.
