Hmm. Let me see if I can remember them. There is one in the breezeway between the Science and Nursing buildings. I think that one is food and drink. There are drink machines in student center. Also, the student lounge on the second floor of Hinton has some as well. I've heard it was food and drink.
Disclaimer: vending machines may come and go due to vendor and school agreements so this might change. If so, please let us know!
