Being loud is not being disorderly. Are they disrupting the business's ability to do business? Puking at the front door...confronting potential patrons...etc. They were paying customers, at a table, being too loud, for you sensibilities.
If you were to use your concealed weapon, after they claimed it was obviously revealed to intimidate (from their viewpoint), for a minor disagreement, you will lose in court.
You will be charged for a criminal offense. You will be sued for everything you will ever have the possibility of owning and your life will never be a happy one from that day forward.
This has a point, the saying "An armed society is a polite one." is moderated by "It is better to be judged by twelve than carried by six." The latter intones the gravity of responsibility for concealed carry.
Guns are for life and death decisions. I could possibly extend that to some vital property issues.
I would NEVER extend it to being loud. If you don't like the establishment's ambiance, find a better one. Let the owner know.

It wasn't concealed. My state allows open carry. It was no more obtrusive than my bald head, and smaller.
I believe that deputies in my state actually make the decision as to want constitutes disorderly conduct.....
Here is the Texas Penal Code on Disorderly Conduct
§ 38.13. HINDERING PROCEEDINGS BY DISORDERLY[0] CONDUCT[0]. (a) A person commits an offense if he intentionally hinders an official proceeding by noise or violent or tumultuous behavior or disturbance. (b) A person commits an offense if he recklessly hinders an official proceeding by noise or violent or tumultuous behavior or disturbance and continues after explicit official request to desist. (c) An offense under this section is a Class A misdemeanor.
Sound advice.
There is a time to turn the other cheek AND a time to stand opposed.
