I’m not sure if your aware of this but there are quite a few large jewish communities that already have kosher hangouts open day and night for anyone to come anytime and take a break with full entertainment and food provided all free of charge etc… Compared to them going and buying a drink etc….
I’m not sure which community you are living in and how large the situation of kids at risk is there. If it’s a large community and the amount of kids at risk is growing then perhaps it’s time for YOU to go to your community leaders/askonim and speak to them about this very serious issue before anyone C”V goes off the derech.
May Hashem give you lots of Hatzlacha in everything
