I did, a little.
I was in a Home Depot here in Florida about 15 years ago and someone noticed the outline of my Kel Tec P11 in my back pocket. It was the pocket pistol to have back then.
When the wife and I exited the store a police officer was waiting for me who stopped me and asked if I had a pistol in my pocket?
I said "yes" and the officer said "don't reach for it, which pocket is it in?"
He removed the Kel Tec, unloaded it and asked for my permit and ID. Once satisfied he returned my credentials and unloaded pistol to me and told me not to reload until I left the parking lot.
Everything was very civil and considering I could have been charged with a crime for violating my permit I was very happy with the result.
