I like no snacks.
I think people don't need to be eating every time they think about it.
The group I belong to has snacks, I come from work and can never bring something. Sometimes I plan to come and then can't, etc. When I do show up, and did not bring anything, I don't eat either. Seems fair, though I don't mind if others don't bring and eat. I am not particularly over-weight, I just figure a little discipline is good for me. Plus I'm a vegetarian and know I love sweets too much. I need to just walk away sometimes...
