Sarge, I have a CC license, however I have no intention of going to a Starbucks where a bunch of wackos are openly carrying guns to do what, demonstrate that they are allowed to do that? They should grow up. Sorry, guns are not toys.

It's lawful, and Starbucks puts itself in a bind because one of the "rights" they're promoting is "Fair Trade Coffee" -- a labor issue with coffee growers, vendors.

Starbucks can't promote one set of rights and deny another.

As for "gun nuts" and "whackos" . . . I don't see anything "disruptive" about a holstered sidearm in public where it's lawful.

If patrons were walking in dressed in cammo with an AK or AR over their shoulder, that's slightly different -- although still lawful.
