I can think of a few San Francisco retail locations where blatant theft happens maybe every 15 minutes. The Walgreens at 9th and Market, the Gateway Safeway, the CVS at Pine and Kearney. The city has a task force for poop (much of the city is treated as a literal toilet); petty theft is almost equally visible and problematic.
The Safeway at 4th and King was basically a free market for crackheads. I lived nearby for five years and I would see shoplifting every time that I entered the store. I'm not even exaggerating.
