Been there. Complained about this very thing on HN, and got shot down. Apparently, individually plastic-wrapped fruits exist because of people with motor disabilities.
I accept that, and I understand that under our economy, it's better (cheaper) for people with such aliments that these fruits are just another item in grocery stores, and not specialty item in special stores (which would be sold for a much higher price). Still, I can't shake the feeling that this is wrong, there must be a better way of supporting people with motor problems than carpet-bombing shops with environmentally absurd individually packaged fruits, and exposing those to regular people without motor problems, some of which will start buying (and thus creating demand) out of convenience or false perception of quality...
