Yes. I tried to come up with clever thematic snacks and failed. If anyone has suggestions, I would be grateful.
So, there's both a sanitation issue (are you moving the snacks with your hands? Are you spending time picking a particular variety out of bowl one to put in bowl two?) and a preference issue; why not just have the snacks in whatever original containers, and have people move some snacks of their choice from the original container to the bowl with each sharing?
