I liked your response as I am an investor in a major bar in SW FL and would hope that any of our security personnel would have the same mindset as you. I do not believe that any of our personnel are armed, but this will make me check to find out. CCW personnel do need to have a different mindset from the average citizen in their homes. So many liabilities are involved.
And I also know your feeling when the one aggressor states he has "something for you". It would be tempting to fill your hand but glad you nor he, did.
