The decision process for a lunch location with colleagues was always very cumbersome, as nobody wanted to take a decision. We normally ended up in one of a handful of locations anyways, so this seemed like a good case to be automated and let a random generator decide.

Code can be found here: github.com/psturm/lunchtime

Features

• users can add new lunch locations (simple list)
• users can mark their preferred locations
• users can "join" today's lunch
• at some point you "spin" the roulette, which selects one of the preferred locations of the group
• participants get a "veto" flag for the selected location
• if threshold of veto is at least 50%, a new location can be selected at random
