Have you ever had a concealed carry fail if so feel free to share. Ill go first

I lost my cell. tore apart the house looking for it. It was getting late and We decided I probably left it at one of the stores we just visited. 1 store no luck second store was already closed. We rushed to the gas station I went in Briefly checked around the store near the things i bought. then rushed up to the register where the guy seemed sketched out and afraid. I thought he might be on something but I Asked if i left my phone there he was like is that all you want in a still scared voice i was like yeah. he said oh ok yeah no there is no phone over here. i thanked him and left when i was getting into the car I realized that my shirt tucked behind my gun and I literally scared the shit out of him thinking i was going to rob the store. I haven't been back in since
