Although this is in keeping with Ben's socially-engaged sensibilities, this is not an entirely altruistic plan; Ben hopes that at the end of the day, he will be able to pay for his expenses and have money left over to go towards his college tuition. There is, after all, some value in watching your fellow man/woman walk away happy and fed (albeit with nitrite-loaded wieners), as hackneyed as that may sound.
Far from being a starry-eyed socialist, Ben is a realist so he is giving this plan a chance to work out. For now, it is a limited time offer, while quantities (for each day) last. If it does work out that people get fed while Ben goes home with some net proceeds, then you might still see Guelph's version of Ed Mirvish (without the wealth)!
If there's a town where this concept has a chance of being feasible, it would be in Guelph. Ben is at the Loonie-Wash property on Essex, near the southwest corner of Wellington and Gordon, most days this summer, when he's not working at his other salaried part-time job. When he goes back to U of G, you may see him at the same place only on weekends, maybe.
