It's a true point albeit a delicate one. I have a colleague who is not the brightest (not a developer ;)) and what I've noticed with him is that there's something of a misunderstanding of social contexts in that he interpretes things others do as in bad faith when they're anything but and which is why in such social contexts he's constantly agitated. So he's simply missing the empathy or emotional intelligence to see things from the viewpoint of another person. He'd be one of the people being annoyed that others don't make room for him but also in the same vein he'd be one of those persons not watching out for others simply because he'd have his head full of thinking about himself and what he wants to buy, he simply wouldn't have the mental capability to think about other shoppers in that moment.
