While it's more excessive in the US, or at least Trader Joe's in my experience, various fruits and vegetables are regularly found in plastic in the European country I live in and others I've visited. Grapes, packs of apples or peaches, various peppers, etc. I find it unnecessary in some of these cases as well, unfortunately. It seemed better in local stalls that are especially plentiful in certain larger cities.

Is this a regional thing? Ours just has fruit and veggies for the taking, like any other supermarket.
