I visited two grocery stores today and after picking up a bag of wet carrots, I wondered again why the need for these things? I figure it must be to clean the produce somehow, or make it looked dewy or something, but I just find it annoying, particularly when the grocery store also stocks these areas with packaged items (like the bag of carrots) or some of the vegetarian items that are sometimes stuck in with the vegetables, while numerous other (usually central) produce shelves go unmisted. No rhyme or reason.
Plus you stand a good chance of getting misted when you reach for something. It just seems like a lot of dampness sitting around for something that isn't particularly useful. Unless there's something I'm missing ?
