My brother and his significant other were at a Wally in the west houston area (westhiemer and dunvale) at 11p.m. this past saturday (going late was first mistake) to buy FE approved calculators for their FE (fundamentals of engineering) exam. The entire time that they are waiting in line, there was an african american male of slightly larger build than him talking very loudly on his cell phone right behind them, from what my brother describes as too close and right in his ear.
So he turns around and says "excuse me but could you back off please," to which the male replies "what, what you saying?" He said this guy had already been drinkning, as he could smell it on his breath and by the way he was acting, AND the only item he had to purchase was another 12 pack. Well, it's now my brother's turn to put his things on the counter and the male behind him ends his phone conversation, never stepping back or moving to give my brother some space, throws his 12 pack up on the counter and says to him "so what were you saying to me? You still got something to say?" and began getting confrontational. My brother then told him nothing man, forget about it because he was carrying and didn't want to escalate the situation any further, to which the male, now in his face says "that's what I thought." My brother was asking me about what consitutes the use of deadly force, say if someone begins threatening to beat your you know what and begins advancing on you? I told him I thought that verbal provocation alone does not justify the use of deadly force, to which he acknowledges and says well what about just presenting my weapon to stop said person from carrying out that threat? So, here I am attempting to pick the minds of the wise ones from this board.
We did agree that the best thing to do in that situation is to not say anything and just go to another checkout line. What stinks is that someone should not have the ability to make you feel so uncomfortable that you have to go somewhere else just to avoid a confrontation/possible shooting that would totally not be worth it. He was still ticked off today but he managed his anger in the heat of the moment and I think did the right thing by de-escalating the situation... Any takers? Sorry for the long read and thank you for your time. 
and scram after seeing that someone is armed and prepared to defend themselves. I also told him that if something were to go down in that situation to keep an eye on the person checking out your items so they don't run off as they should be a valuable witness and able to second your story. 
Exactly what I told him mgood! Now that you have your chl, your not just carrying a firearm with you, but also a big responsibility, and with that responsibility your just going to have to start sucking it up and take it and learn how to ignore the petty things that used to bother you.
