I would rather of course if they have smart phones made all work and setup those vending machines and than stop there. It is possible to track transactions and all those people can have one or two penalties.( Meaning you can only but what's there and you can't gamble or whatever do.) All this thing with camera monitoring for me personally if very disrespectful.
If I would donate any sats it would be from my heart and won't look at what's happening there as majority would do the same. For those curious or those who think it's only right to spend donated at those machines let's make monitoring more descrete.
