Welcome to the forum Catfish! Open Carry is intimidating at first. After awhile it will be like grabbing your cell before you head out - just natural. And you'll soon quit thinking everyone is looking at you.
I would like to caution you on something as it never crossed my mind until it happened to me and that is what to do DIFFERENTLY now that you are Open Carrying. You will have to be of the mindset that it is better to flee than to fight simply because you are now carrying a deadly weapon (and everyone knows it) so that means if you end up in a fight, most likely someone is getting shot / killed.
I was in a McDs with the wife when some stupid high school kids started making comments about my gun along the lines of "...let me go get my shotgun and then we'll see what'll happen..." See the problem here? If I had no gun (and assuming they didn't either) and some kids wanted to start something then, well, worst thing to happen would be someone getting beat up. BUT, there is NO DOUBT now that there is a gun in the mix.
Do I say something back and let it escalate into a physical confrontation? ABSOLUTELY NOT! Under no circumstances can I allow my gun to fall into someone else's hands, which could happen in a fight. And am I willing to shoot some idiot kid that is probably just mouthing off being silly as he never said anything directly to me, but rather just loud enough that I could hear it? I can't even say something of reason to them because what if they rush me and now I HAVE to pull.
See the dilemma? In a situation that you would have otherwise had no second thoughts about allowing yourself into, you now must SERIOUSLY consider flight over fight for if you don't, someone is going to the hospital and someone to jail. I can read the headlines now - "Gun nut kills teen over argument".
Carrying a firearm not only requires you to have self-control and responsibility, it actually helps one to build both.
I ignored them and left quietly when we were finished. I should have left immediately.
Think you did fine. Now if they had gotten up and headed out first, I might have made my exit soon thereafter if I could do so w/o a confrontation.
I likely would have set my digital recorder upright on the table and possibly taken a quick picture of the group. Any escalation of the perceived threats would have generated a 911 call. I do not suffer fools lightly.
