Ok, as a government worker I normally stay in my one building and stick to the same hallways and ect. So everyone who knows I vape aren't surprised at all when I use my Chuck. Although I was taking a trip to a government agency headquarters and under a routine inspection of me and my vehicle they noticed my chuck... well let me explain to you the problem with the chuck, it looks EXACTLY like a homemade detonator... so you can imagine the shocking and frightening looks I got from all the guards. lol Anyway they asked what it is, I told them and quickly put it up to my mouth and pressed the button, might I add as I pressed the button a guard shielded his face as to protect himself from a bomb detonation lol and blew out some vapor. A few guards told me about what they thought it was initially and I never thought about it like that before. I took 5 min to tell them about it and gave them this website. Very funny and entertaining in my opinion. lol
