To summarize...
It is okay for a person with a firearm to impose his will on others, even though they are acting in a legal manner.
By displaying the weapon, which you give credit for "changing the behavior of the rowdies," (my words) there was an implicit threat. You can lawyer that statement all you want, but your words indicate an intent to threaten.
You do not have a right to a quiet breakfast. There was no threat of injury to you or anyone else.
I support the right to carry. I do not support the right to threaten in any way those whose behavior you do not like. Your original post indicates that was your intent.
This act showed extremely poor judgment for a number of reasons. The idea that you think you can "out-lawyer" your actions by saying you never touched your weapon, only displayed it, does not change that fact.
Drunk and disorderly in public is legal? Let's party, Dude!
