I guess I'm lucky.
I can carry while at my workplace, with the blessing of the company's owner.
I've cleaned guns over lunch hour in the parking lot before. Did some last Thursday in the breakroom before employees arrived. I've even (shh!) bought and sold guns at work (oh noes!).
I've (ETA: 'also') got a pistol in the safe under my desk along with two extra mags. And another 100 rounds, just in case the zombies come out and I can't get to the car.
