That building looks too "official" to be a donut (or doughnut) shop. I suspect:

1. It used to be a church, but the lobby coffee shop saw an opportunity and took over.
2. It was the old police station and some ex-cops seized the opportunity (should I have used cops and seized in the same sentence in this context?).
3. It's a front for drug dealers to keep cops occupied.
4. It was once a grocery store (looks like a loading ramp?). They couldn't keep donuts in stock and everything else except coffee was sitting on the shop past its expiration date. They do sell beer in the back though.
5. There are no coincidences.
