You forgot to read the last paragraph.

For what it’s worth, Chipotle’s “gun ban” is actually more of a polite suggestion, and the chain’s statement acknowledges that “there are strong arguments on both sides of this issue” and the “vast majority of gun owners are responsible citizens and we appreciate them honoring this request. And we hope that our customers who oppose the carrying of guns in public agree with us that it is the role of elected officials and the legislative process to set policy in this area, not the role of businesses like Chipotle.”

There's a reason why people i know carry CONCEALED.
