A non-snacking professor
I have a strange dilemma. I teach college chemistry and I have this policy that if a student needs to borrow a calculator during an exam, I will loan them one for $5 and the money goes towards snacks for the class. They also have the option of bringing snacks next class. After a couple classes with snacks, some students have suggested that we just regularly bring snacks, have a potluck, etc. This is a 3 hour class, I understand having food helps learning. I have never had any of the snacks they bring in because I don't have the presence of mind to control my snacking when I'm focused on teaching. Plus I'm talking, I don't want my mouth full. Also, most of the snacks are not super healthy options like chips, oreos and soda. Most of the snacks don't really interest me much.
No one has mentioned that I never eat the snacks, but I'm not sure what to say if someone asks. With friends it's fine to explain, but it feels a bit too personal with students.
