Tattoo parlors. Strip clubs. Hole-in-the-wall liquor stores. Pull-tab joints. Attended laundromats (people who live in bad neighborhoods don't have their own washers and dryers, and ones that are inside apartment buildings tend to get vandalized/broken into).
I imagine liquor stores that sell pull-tabs. I'm unaware of stores dedicated to selling pull-tabs but there are a lot of corner liquor stores that are more or less frequented by people purchasing pull-tabs and cigarettes more than anything else.
