I do better than this when it's my turn, but I tend to be minimalist for a specific reason. If you start putting out good snacks, then it suddenly becomes a competition (especially among women of my generation), and people are intimidated from volunteering to do coffee this week.
I did fat grapes for the children until I realised we are not well-places to do choking hazards. I did cheap donuts, Nillas, or sugar wafers but got tired of the sugar-grumblings from the young mothers who still believe the myth that it causes their kids to be hyper. So now I do Goldfish, and cheese and crackers.
Swedes care about coffee, but we aren't as Swedish in the Covenant as we used to be.
