It's great that you conducted the survey on dietary preferences, but I was upset that kosher wasn't an option. As someone who keeps kosher on campus I often end up eating vegetarian, despite that it is not my preference. I also think that there are more people on campus who keep kosher than you think.
We agree that it would be great to have more dietary information to assist our planning, including Kosher (or Kosher-Style), Halal, Gluten-Free, Lactose Intolerant, etc. However, that would require a different survey method, and could not be done through our cash registers, which cannot be configured to accommodate surveys of multiple, overlapping categories. This is also a longitudinal study, designed to have the same questions each time (this was the third identical survey).
