I know a couple who run a grocery in one of the worse areas of Cleveland. They list many issues - shoplifting, costs for security, a narrow range of products are bought (mostly cheap ones, snacks, soda), unreliable employees - they would like to be able to sell out one day, but they know no one would buy their business.
I know about the shop lifting (having witnessed it first hand). Didn't think about the unreliable employees and the fact that only junk food and soda were the big range items selling.
Those people owning that store are screwed. It's a pity.
