Chipotle interview questions

I applied online and received an e-mail about a week later asking to come by for a job fair interview. It was a group interview with myself, 5 other applicants and an apprentice who did the interviewing. The questions were pretty generic, why do you want to work here, what does food with integrity mean to you, what job experience do you have, etc. I felt that the interview went exceptionally well, the manager, Esme, made direct eye contact with me the entire time, more so than any of the other applicants. She seemed to really like my answers, and even referred to my answers throughout the interview as she explained the company. At the end of the interview she addressed the group, but kept eye focus on me when she told us to expect an e-mail or phone call my Friday to set up a second interview. I walked out of the restaurant feeling like i aced it and was definitely going to get that second interview. About 5 hours later i received an email saying that after reviewing my application, they were unable to offer me a position at this time. I was honestly extremely shocked and disappointed by the email. As i said, i thought the interview went extremely well, so i'm not quite sure why i didn't make the cut, but i guess that's just how it goes sometimes. I am tempted to call and just ask them why, but i don't think i will. I just want to know!!
