I live on a university campus. There is a McDonalds here, and that's it as far as chain-fast food places go. If I go to the trouble of traveling downtown, it is usually somewhat of a special occasion, and so if I am out eating usually it is somewhere nice. Also,the food vendors on campus tend to be much better than most fast food places. There are about 5 different sit-down restaurants, ~20 different food vendors, and about 4 pubs. However, if there were more fast food places on campus I doubt I would go to them often anyways. The frequency might increase from "never" to a few times a year.
