I've gone into a few stores looking for accessories or whatnot for the gun I am carrying on me at the time...I always thought it was just plain good form to warn the salesperson before I just whipped it out.
If they need to unload it for some reason, I let them do it - they are insured, I'm not
No kidding they don't work, we've had a signs up for a month now where I work stating that the restrooms are not open. Want to know how many people ask me daily where the restrooms are?
