Review of QDOBA Mexican Eats

I have eaten at a few Qdobas & never gotten sick. However at this particular location at the Indianapolis airport, I asked to verify that the meat was still gluten-free since I had not been in a while. The server told me, "Nothing is gluten-free here." I thought maybe she just did not know what gluten-free meant, so I asked to speak with the manager. He came out waving his hands and told me very dismissively, "We have nothing you can eat here. Nothing." I said I understood they could not guarantee no cross contamination, I just wanted to know if it had gluten ingredients. He wouldn't elaborate, he just kept saying, "We have nothing gluten free." He clearly just wanted me to leave. I have really "lost my appetite" for Qdoba now. I don't think I will ever go back.
