It's inappropriate in today's era but not unprecedented for a president (e.g, if this was Harry Truman, he not only would have called out Nordstrom, but then would have threatened to punch their CEO in the face to boot). As a self-admitted right-wing extremist that didn't vote for Trump because he wasn't the right kind of conservative for me, this is the kind of thing that bothers me the least about Trump. If anything I hope he just picks better targets in the future (e.g. pharma companies). If Obama or Clinton had done it the initial shock factor may have been greater, but only because Trump has such a long history of being an egomaniac and sleazeball.
