Alum here. Any special precautions taken at dining halls? At least the great majority of undergrads have to eat at large dining halls like Arrillaga and Lakeside, that seems to be an even greater problem than in-person classes, especially when people reuse dishes. I recall Ricker Dining’s manager occasionally patrolling the dining hall telling people not to reuse dishes back when I was a student living in GovCo. Apparently a lot of people do that.

Afaik all they've done is barred non-students/staff from the dining halls. There might be other precautions being taken that I'm not aware of, however.
