A+ dude! You sound like a very mature 19 year old young man. You were correct in your actions and conduct in my opinion. The fact that there was no sign on the door gives you right to carry into that store regardless of whether it is open or concealed, however when confronted by an owner/manager who represents the business and they personally request that you not have your fire arm in the store you have two options. do what you did and put it in the car, or tell him that you will conceal it for him. without policy put somewhere for patrons to be able to see it he cant legally make you put your gun in your car unless he owns the business or property. A manager can request that you conceal it if he wishes due to the fact that he may feel hes losing business because of the publics view on it. (its a sad world we live in). Without a posted sign in a conspicuous place, the law is on your side for being allowed to conceal in that business. Openly carrying is a little different if the owner feels against it however.
Awesome work all in all man, keep on keepin on.
Nice gun too I own a Beretta Px4 Storm subcompact in .40 cal and carry openly or concealed as often as possible.
Thanks for the post dude.
What part of the state are you in?
