I don't think it's a problem. Most people would feel insulted if you offer money when bumming a cigarette. It's like "Dude !". Cash is vulgar in the "bumming" frame. The way to reframe it if you really want to pay is to say: "Can you sell me a cigarette?" and not bum it. But even then, people will tend to give it to you for free. So unless the person is really poor, they won't accept money. And even then, there's some "I'm poor but generous" going on. It's an interesting concept, though. But in my opinion, one should remove cash from the equation. The other question that would arise would be : If you remove cash, then a person could have to lose after having so many bummers come to them. This can easily be solved by fixing how many cigarettes a person could give before disappearing from the map to bummers. The "pack-owner" can set the number to 5 if in a good mood, after being bummed five times, he disappears from the app for that day or something. Though it's amazing how prices vary: A pack here is about two bucks.. And, as you might have imagined, when there's a difference of potential, current flows: There's contraband and people smuggling cigarettes from here to Europe (France, especially). The average pure profit is 1,200 euros a trip (after accounting for all expenses, room, plane tickets, nights out...).
