I can't carry at work - yes they randomly check and violating it would have me in cuffs, fired, and probably prosecuted. I'm not a Clinton after all. However, I do carry everywhere else. Everywhere. That's why it's called concealed carry. In my state, if discovered on business premises they can ask me to leave and I must (else be charged with trespass and or causing a disturbance). But I conveniently "miss" seeing any signs saying "no firearms"... Although if possible I don't patronize such businesses anyway.
Most medical offices in Oregon have signs saying no firearms...I know an old lady who ignores the signs.
