Never been asked by any of my doctors. My GP was career Army as a doctor and retired in the last few years and moved to this area to practice, so not sure if I'm more or less surprised for him.
On the other hand, a coworker, well now former coworker since he left for the other job, applied to work for the Sheriff's Dept in the next county as a corrections deputy. They asked him how many guns he owns, if he specifically owned any ARs and asked for brands and calibers, etc.. Seemed a bit excessive but I understand it is law enforcement so at least its pertinent in that case.
