I couldn't agree with you more. I have, however, actually been to a Food Lion and it was quite filthy, the meat section wasn't appetizing either. That was about 10 years ago.
You speak as though this were a singular event ... I take it Food Lion stores are not common in your neck of the woods? They're quite common in Virginia ... some are in better shape than others. I do consider them near the bottom of the supermarket barrel (and rarely shop at them), but the newer stores aren't too bad.
