it is true we don't think GM foods are going to turn us into the zombie apocalypse....but in your example, I'm sure the grocery store isn't throwing away half their apples because they forgot to tell their supplier not to send GM foods......of course, in reality I am assuming your example is a lie.....
Here is the intro to a recent survey:
UK supermarkets reject 'wasted food' report claims

The report said half the food bought in Europe and the US ended up in the bin
Britain's biggest supermarkets have been defending their practices after a report suggested that up to half of the world's food is thrown away.
The Institution of Mechanical Engineers said the waste was being caused by poor storage, strict sell-by dates, bulk offers and consumer fussiness.
The British Retail Consortium said supermarkets have "adopted a range of approaches" to combat waste.
They also lobbied the EU to relax laws stopping the sale of misshaped produce.
According to the report - Global Food; Waste Not, Want Not - from the UK-based institution, as much as half of the world's food, amounting to two billion tonnes worth, is wasted.
You may argue that it is not necessarily 50% from supermarkets if you wish. But to state that we (the world) must increase the amount of agriculural land or develop more GM foods is totally misleading.
We are growing the wrong stuff in the wrong places and dumbing down users to accept only what the supermarkets tell them is 'perfect' food.

This waste is as a direct result of supermarket policy. If the apples or tomatoes are of odd shapes and sizes they cannot be handled by machine and computer, but the supermarkets maintain that customers demand 'perfectly shaped' food. That, as even you must agree, is total bollocks.
You mention the 'grocery store'. In English a grocery store is NOT a supermarket - perhaps it is in america! We need to get back to high street shops, to green grocers, to butchers, to fishmongers where we pay for the produce and the wellbeing of the tradesman and not a million faceless shareholders. We need to be able to tap into the expertise of these people for our own health's sake. We need to understand seasonality of food and not demand strawberries in winter because the only strawberries available in winter are either genetically modified and tasteless or they have been flown in from California and we are paying for PanAm or British Airways and not for strawberries!
In short we need to stop believing the BULLSHIT that Wallmart, Safeway, Tesco et al employ thousands of expensive copy writers to feed us.
A final point on GM foods. The question is NOT that they may be harmful, that is quite unlikely. The battle must be fought so the farmers are not held to ransome by private, profit run organisations.
You are fighting the wrong battle.
