A club in the university I attend came up with meals on wheels for students. The basic idea is that students get too stressed or busy to cook during exam times, thus, for a minimal fee, they will be provided with home cooked food.
Honestly this is not the first time the idea has cropped up. My cousin use to have his own food serving business where he charged people to buy and deliver food during exam time.
It is an interesting idea which has potential since its target customers, students, are always desperate for food and extra time.
