Unless you live where I do, where people steal mass amounts of junk food from convenience stores and then resell it at the nighttime markets to our struggling, marginalized, population of unhoused folks at an exploitative mark-up.
Because that is actively harming me, and the community I live in.
Though even with all that, confronting or reporting them isn't helpful. But if asked, and I saw it, I would say so.
They sell it at higher prices to the mentally ill and drug addicted people who are at those markets which are usually referred to as "open air drug markets." I don't like that term but it may give you reference to how this harms the community, though.
