I think the man has a good point demonstrating his right to openly carry a gun in public, but he was in a privately operated business so if he wished to protest the business he was going about it all wrong. He should have gotten a sign and stood out in front of the business and protested that they do not allow people to open carry when in their establishment. Personally, I don't think he has the right openly display his weapon in the coffee shop and just should have covered it and when he left the building uncovered it if he wished.
