You're the third person I've seen OC in the store. I always use an OC sighting in the store as an opportunity to educate my coworkers about our policies and the laws regarding OC. All of our Loss Prevention staff and our managers know that OC is legal and not against our policies (I made sure of that). A few of them think it's stupid, but I don't care; haters gonna hate. At least they know they aren't allowed to do anything about it.
Best Buy has publicly announced that their policy is to abide by state law in regards to OC (can't find the link, sorry). That means they are OC-friendly in states that allow it (like WA), so I hope to see more of you there!
