I dunno. Oftentimes desperate people are more liable to steal from those stores than to steal from Walmart because the security is more lax. people like to say that, oh, Walmart builds it into their budgets, the theft, so they do nothing about it, but that's totally false, there are plenty of instances where Walmart or whatever other shitass big box store will call the cops or try to detain you with their personal security. Not to say that people should rob local businesses over Walmart if they have the choice, right, but that's why people might do it.
