There's only one Walgreens on Telegraph in Oakland: 5505 Telegraph. It's this one.
Not far from Children's Hospital. Part of a shopping center with Noah's Bagels, Round Table Pizza, and a post office.
If you're local, it's definitely worth calling or stopping by to ask which of your normal purchases, especially medications, might not be available based on the religious biases of some of their staff.
And keep pestering them until that pharmacist is fired. And they say so publicly.
The news article mentioned the victim's name but not the pharmacist's. (This is a liability thing; journalists have to be very careful about whose names they throw around or they or their news host can be sued.)
Walgreens needs to become aware that (1) they are going to be subject to a whole lot of very annoying calls (and possibly visits) until they declare that bigotry in their staff is not welcome, and (2) it's a really bad idea for patients to be unwilling to tell pharmacists anything about their condition, and this guy is undermining public trust in the medical profession as a whole.
A medical professional who can't do their job for "religious reasons," if they can't just fire the person, should have to make it very very clear to customers that they provide limited services.
Maybe they can wear a button that says "I WILL NOT HANDLE SOME MEDICATIONS," possibly with a nice list that can be handed out on request. Of course, the pharmacy would need to always have another person on hand for their shifts; they can't have someone working alone who can't serve the customers, but as long as they're always paired with someone who can, it's not a problem.
("Just fire the asshole" is by far the preferred route. But he may actually be looking for that; he may have a neo-nazi legal team ready to jump in and sue the company for firing someone "based on their religious beliefs.")
