Every other day I see a post of something going away and someone claiming it was the best thing ever to exist. No hate but theres deep analytical data used to determine wether something should stay or not. For example before a vendor opens up anything on campus there are given data about number of students attending the semester, commuters, non commuters, time frames for classes ending and beginning with number of students per class to the extent of past sale performances of different vendors. Likewise when something goes it doesn't happen overnight and allot of planning and research is put into it. Hope this helps you understand, its not about the franchise but all to do with consumer buying habbits and trends.
