Interesting day... had a few folks in from California (SF area). Eating lunch, and a guy at a table near us dressed up has the tails of his suit spread and... a Glock is tucked in the small of his back, butt sticking way out of the suit. Cali #1 comments that the guy has a gun! Others are shocked and ask if that is legal. Sould we call the police? One stated he had never seen a gun anywhere other than one on a police officer or in a movie. I assured them that not only was it legal, it was common, and there was no need for alarm. A waiter noticed and was pointing to the guy and clearly telling co-workers the guy had a gun. Trying to be the nice guy, as I was walking past the gun-toting "lunatic", I quietly said "Just so you know, your gun is visible, and some patrons are expressing concern." and gave a quick smile. He smiled and said thanks, and covered the gun. I didn't care, but didn't want to see they guy hassled. My helpfullness was all for naught. Some folks came up and talked to him, and we overheard him and his dining companion laugh, and gently explain their job involved guns, being employess of the ATF! They produced credentials, and I felt a little silly for trying to help him. For all I know he prefers to carry for easy access and may have had the coat tail intentionally tucked behind his gun for a quick draw! Oh well! Good intentions!
