Why is it so hard for a fast food chain to avoid cross-contamination vs. other restaurants? Is it because they don't train workers properly?
What Chipotle experienced was more than what you'd expect to happen in well-run restaurants that prepare everything themselves.
Again, it's not willful or malicious, just laziness.
I don't know if that was intentional or not, but I like it! :)
A lot of it, I would guess, is simple scale. There's like 800 more Chipotle restaurants than Chili's, and I'd be damn sure the volume of meals coming out of each one is skewed far towards Chipotle as well.
