In gm-techniques there are lots of questions and answers that mention snacks (One example). Those questions are usually broader than just snacks, and I can't find any question that's only about snacks.
Would a question solely about snacks be on topic? The question I'm thinking about came about because it seems that at some of my sessions, players are more or less awake by the end of the session depending on what snacks are offered.
So I want to ask about what type of snacks people have had experience with over lengthy gaming sessions, and how well they did at keeping players awake & active over the duration.
