I think the reason this is something I give thought to is because I've had bad experiences related to it.
I've had two (former) co-workers that randomly threw their permits on the desk at work like a challenge coin. I had one trainee ask me in the middle of training if I had a permit (WTF would you even ask some random stranger that? Especially given that random stranger is your supervisor and can get you sent to security guard Siberia /the impound lot on third shift/ with a single phone call)
I had one guy that used to preach the Gospel of Nutnfancy to me every time he saw me and tell me that if I wasn't a member of the NRA I was a blood sucking leach on the back of honest gun owners and if didn't have a permit I was failing in my civic sheepdog duty. Finally, there was the dumbfuck who came to work at LEAST once a week with some breathless story about how he came THAT close to having to shoot someone but "they noticed my CCW and thought twice."
I swear to God I've had each and everyone of these interactions and somewhere along the line I decided I wasn't EVER going to be THAT GUY.
