I'd say it's just a fluke. I know Subways can vary in quality by quite a lot. There are 3 by me within a 5 mile radius of each other. One of them is always manned by a thug, one has Raid ant traps on the couter tops, and the other one is just right. I was in one in White Plains that was outstanding. Very clean and efficient. Usually Subway is manned by only one or two people. The White Plains one had at least 4.

I think Subway's bread is what keeps me coming back. I know the meat is mysterious and the veggies could be fresher, but that bread rocks.
