For some more context this place, reems, really isn’t a bakery so much as a middle eastern take out place. The main store is currently closed down though so the only place they have open is a counter serve food court style place in the ferry building, so the cops didn’t get kicked out of the place, they either went to the counter and the cashier refused to serve, or more likely, they saw the new policy online and threw a hissy fit without actually going.
The founder is a Palestinian leftist, so this probably was targeted towards cops/military.
I’d highly recommend going here if your on a tourist trip and end up in the ferry building, not just for the cop hate, but there wraps are great as well.
