Bad Time At Fox Theater Tucson

Part of the Dark side of Tucson ... Bad experience today at Walmart in Marana.... I walked into the store to buy a few items.. of course I had my weapon on, in the open as you can carry open here,,, 45 long Colt holstered... I was half way down an isle and an older women stopped in the middle of the isle to talk to this younger guy, mid 30's.. I waited a minute or two then politely said "excuse me mam". No response.... Again I waited and said a little louder "excuse me mam"". She turned and looked at me with an F you look for what seemed like forever... She then started top stutter. Realizing she had something wrong with her, I started to back up to find another path.. just then the guy says " watch it buddy" I state OK and he kept on "my mother has brain damage she was in a coma... I stated "I am sorry I did not know.. I did say excuse me" he then proceed to call me vulgar names.. me being me did not back down . I said to him that i was sorry let it go... NO he would not... he then throws his arms up in the air and looks at my gun and says" Oh you going to draw on me in the middle of Walmart. I kept my hand on the cart and told him he was an idiot... Now she starts on me in very cognitive speech " oh he thinks he is a big man because he is wearing a gun" Now i am mad but kept my cool.. I state oh no it has nothing to do with the gun.... He is still trying to goat me into a confrontation of some kind, calling me all kinds of names and telling me he is going to call the police on me ( I know not what for)... Wanting to beat the crap out of this asshole, I counted to ten and walked away as they kept shouting crap at me...... What have we become?????
