I was recently at Piazza studying between classes. I was approached by a staff member asking me if I had made a purchase at Piazza. I told her I had not. She said Piazza was ONLY to be used by customers who make purchases from Piazza; it is NOT for general use or for people who have made purchases at the Shop. This was very disappointing to be asked to leave as I am certain that this is a general student area. Can this be addressed?
