Where do you live? The Chipotle's in my area are very clean. I've never seen a filthy Chipotle's. Of course I live in Silicon Valley so there is fierce competition for these type of restaurants.
The two I know about locally, are really clean and well-maintained. I'm guessing that Chipotle did something politically incorrect for the extreme right wing?
It looks like we're getting the mirror image of the Chick-fil-A flap.
BTW, I deplore what Chick-fil-A's owner has done, but their food is pretty good, so I go there every now and then.
Why would I be dumb enough to inconvenience myself by avoiding it? Some people are way too serious about this stuff.
