@twinsmama - same situation at my daughter’s school, previously cloaked in anonymity, which I will also name, the University of Cincinnati. Only one dining hall open on the weekends for limited hours, and it’s even more limited on game days.
I once asked food service why, and they said the kids never use the dining halls much on the weekends (but some report lines at the one that is open, ironically the one furthest from the freshman dorms). I asked them, nicely, how they would know this if they didn’t at least keep more than one open and get some fresh data.
They never emailed back, lol.
