I too carry every day at work, (at a bank). I am not worried about a robbery as most are note passers these days. I am more worried about walking to and from the truck at opening and closing. That is when I feel the most exposed. Ironically, the only robbery I have been present for, the nitwits approached the armed currier servicing the ATM, Currier drew down on the BG’s and that was the end of it. Probably the only time the currier touched his gun in his whole career.
On that note, I feel the least at ease when I am at a different location for training or the like, and we carpool to lunch, I really fear the unexpected 30.06 while with co-workers. Only happened once, (taco cabaña) it was easy to say, I don’t eat there, “TC does not agree with me”

subway is just fine.
I question the PO carry, ironically I have decided I will visit the PO Boxes, but not the counter. They are separated in most every PO I have been in. i WILL NOT go to the POBox at night with out
