Welcome back!
yeah, there's a few things in neo that are a bit daunting to get into (again). Foodclub is a change/luck you're playing with, but there's strategy behind it too (that's why we follow other people's bets). It's just that you have to do it multiple days to see an overall positive outcome.
Also, there's an app, ghoul catchers, that can easily make you 50k a day. Just replay the first level and you can make it in 15min
